olga2289 [7]

Answer:

x = 24.52

Step-by-step explanation:

Since this is a right triangle, use Pythagorean Theorem to solve for the hypotenuse.

Pythagorean Theorem: a² + b² = c²

24² + 5² = x²

576 + 25 = x²

601 = x²

√601 = x

This question<br>find the value of x y and z​
Klio2033 [76]

Answer:

x = 6

y = 24

z = there is no z?

Step-by-step explanation:

All angles of a polygon add up to 360 degrees

The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side

3y + 18 = 90

3y = 72

y = 24

15x + 30 + 10x = 180

25x = 150

x = 6
