Is there a triangle whose sides are of length 2cm 3cm and 5cm?

Let angle D be an acute angle such that  D=0. 33. The measure of angle D is 70.7 degree.

Acute Angle:

An angle is formed when two rays meet at a vertex. If this angle is less than 90°, it is called an acute angle. In the image below, the angle formed between "Ray 1" and "Ray 2" is acute. Bisecting a right angle also creates two acute angles.

Inverse Cosine :

Inverse cosine is the important inverse trigonometric function. Mathematically, it is written cos-1(x) and is the inverse of the trigonometric cosine cos(x). Note that arc cosine is not the reciprocal of cos x. There are six inverse trigonometric functions like sin-1x, cos-1x, tan-1x, csc-1x, sec-1x, cot-1x. The arc cosine is used to determine angular measurements from the trigonometric ratio cos x values.

According to the question:

To approximate the measure of angle D, we will need to use the inverse cosine function on our calculator. All calculators vary, so I am not sure where you would find the button for it on your calculator. However, I know many calculators have it so you click the second button, then cos

 cos(D) = 0.33

⇒ D = cos^-1 (0.33)

⇒ D = 70.7 degrees

Answer:34.5

Step-by-step explanation:

To multiply two mixed numbers, you can convert them to improper fractions and then multiply the numerators and denominators separately.

2 1/5 can be written as (2 x 5 + 1) / 5 = 11/5

2 2/3 can be written as (2 x 3 + 2) / 3 = 8/3

So the product of 2 1/5 x 2 2/3 is (11/5) * (8/3) = 88/15 which is equivalent to 5 8/15 or 5.533 repeating (if you want to express it as decimal)

You can simplify 88/15 by dividing both numerator and denominator by the greatest common divisor (GCD) which is 1 in this case, so the final result is 88/15.

The distance between the line and the point is 8 units.

When two parallel lines intersect, a two-dimensional coordinate plane called the cartesian plane is created. The horizontal line is the X-axis, while the vertical line is the Y-axis. If the sign of x is positive, the coordinate point (x, y) in the Cartesian plane indicates that the point is on the right of the origin; otherwise, it indicates that the position is on the left of the origin.

Given a line L,

The 3-4-5 rule is a rule that states that in any right triangle, the ratio of the length of the two shorter sides will be 3:4 if the length of the hypotenuse is 5.

To determine if a triangle is a 3-4-5 triangle, you can use the following steps:

Divide the length of the hypotenuse by 5: 10 / 5 = 2

Multiply the result by 4: 2 x 4 = 8

Multiply the result by 3: 2 x 3 = 6

So, the triangle has sides of 6, 8, and 10 units, which is a multiple of 3-4-5 triangle and it is a right triangle.

Note that not all triangles that have sides in the ratio 3:4:5 will be a right triangle, only those that have a 90-degree angle are considered as a right triangle.

The equation of the perpendicular line is y = -7/2(x + 5) + 2

From the question, we have the following parameters that can be used in our computation:

y=2/7x-8

Also, from the question;

We have the following points

Point = (-4, 2) i.e.  (x, y) = (-4, 2)

The equation of a line can be represented as

y = mx + c

Where

Slope = m

By comparing the equations, we have the following

m = 2/7

This means that the slope is 2/7

The slopes of perpendicular lines are opposite reciprocals

This means that the slope of the other line is -7/2

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = -7/2

(x₁, y₁) = (-4, 2)

So, we have

y = -7/2(x + 5) + 2

Comparing the provided equations in the options with the slope-intercept form y = mx + c and with the intercept value given , The answer is option A and B.

An equation is a statement of equality between two expressions. It typically includes numbers and mathematical operations such as addition, subtraction, multiplication, and division. For example, the equation 2x + 3 = 7 is a statement that the value of the expression 2x + 3 is equal to the value of 7. Equations can also include variables, which represent unknown values that can be solved for.

In a linear equation, the slope (also called the gradient) is a measure of the steepness of the line, and the y-intercept is the point at which the line crosses the y-axis. The slope of a linear equation can be represented as m in the form of y = mx + b, where m is the coefficient of x, and b is y-intercept. The y-intercept is the point where the line crosses the y-axis, which can be represented by the value of b in the form of y = mx + b.

Start with the compass's point on vertex L while maintaining the same distance, and then draw a curve that intersects the line connecting L and C.

Centre of dilation  of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

An operation that moves, flips, or otherwise alters a figure to produce a new figure is called a transformation. Rigid transformations maintain size, whereas non-rigid transformations do not. A dilatation enlarges or reduces a figure while maintaining its original shape. To put it another way, the dilatation resembles the original. Every dilatation has a scale factor and a centre. The scale factor indicates how much the figure stretches or contracts, and the centre serves as the point of reference for the dilation (much like the vanishing point in a perspective drawing). A scale factor is usually identified by a label and is never zero. Additionally, the dilatation would be if the original figure were labelled, for example.

The linear equation [ ( 2x PLUS y ) EQUALS 10 ] has only one solution.

A linear equation is an algebraic equation having the form y=mx+b, involving only a constant and a first-order (linear) term, where b is the y-intercept and m is the slope. Occasionally, the above is called a 'linear equation of two variables,' where x and y are the variables.

Now solve the given linear equation which is:

[ ( 2x + y ) = 10  ]

Now solve this equation in order to determine the number of solutions it has,

( 2x + y ) = 10

( 2x + (10 - 2x)) = 10

( 2x + 10 - 2x) = 10

( 2x + 10 - 2x) = 10

(10) = (10)

Since 10 = 10 is correct, therefore, the equation  ( 2x + y ) = 10 has only one solution.

The number of cubic yards of each component needed are 3.99 cubic yards of cement, 7.97 cubic yards of sand  and 15.94 cubic yards of gravel

Ratio is used to compare two or more quantities. It is used to indicate how big or small a quantity is when compared to another

Since a total of 18.6 cu yd of concrete is required and the total amount of these components must be 1½ times the volume of concrete needed. We can say:

total amount of these components = 1½ × 18.6 cu yd = 27.9 cu yd

Also, since the ratio of cement to sand to gravel for this application is 1:2:4. We have:

Total share = 1 + 2 + 4 = 7

cement = 1/7  × 27.9 =  3.99 cubic yards
