What is the value of x?

andrey2020 [161]

Answer:

x = 30°.

Step-by-step explanation:

To calculate the value of 'x', we can first derive the value of one of the angles that make up the triangle.

Notice that there is an angle with a measure of 100°. The angle that makes up the angle of the triangle is called a Vertical Angle. Therefore, if the angle in red is 100°, the vertical angle, or the third angle of the triangle, is 100°.

There are two congruent sides to the triangle, as seen by the congruent lines. This means that both of the other two angles must be equal. Find the value of 'x' by:

180 - 100 = 80. Since the value of one angle was 100°, and the angles in a triangle must add up to 180°, you can simply subtract to find the sum of the other two angles.

(x + 10) + (x + 10) = 80

2x + 20 = 80

2x = 60

x = 30°.

Write a proportion for the statement. 40 is to 10 as 32 is to 8.

All proportions have this form:

$\sf{\dfrac{a}{b}=\dfrac{c}{d}}$ , Where $\sf{\dfrac{a}{b}}$ is equal to $\sf{\dfrac{c}{d}}$ .

If $\sf{\dfrac{a}{b}\neq\dfrac{c}{d}}$ , it's not a proportion.

_________________________

Here we have two pairs of numbers:

40,10 and 32,8.

Written As a proportion, they look like :

$\sf{\dfrac{40}{10}=\dfrac{32}{8}}$

Hope this made sense to you :)

5. Patricia is on the edge of the top of a mountain and notices that a kayak on the lake is 30 meters

zhuklara [117]

The distance from the kayak to the mountain to the nearest whole number is 43 meters.

The situation will form a right angle triangle as shown below in the diagram.

<h3>Properties of a right angle triangle:</h3>

One of its angle is 90 degrees.
The sides and angle can be found by using trigonometric ratios.

The height(opposite side) of the triangle is the kayak distance from the mountain to the lake below. The distance from the kayak to the mountain is the adjacent side of the triangle.

Therefore, using trigonometric ratios,

tan 35 = opposite / adjacent

tan 35° = 30 / a

a = 30 / tan 35°

a = 30 / 0.70020753821

a = 42.8444402023

a = 42.84 meters

a ≈ 43 meters

Which statement can be used to prove that a given parallelogram is a rectangle? The diagonals of the parallelogram are perpendic

liubo4ka [24]

The answer in this question is B The diagonals of the parallelogram are congruent because that's only possible for right angle quadrilaterals. We can say that the diagonals of the parallelogram are congruent. The diagonals of this figures have the same size and shape.
