Question

Find the value of x please help the image is attached below.

Answer 1

x = 85

Explanation:

using Pythagoras' identity in the right triangle

The square on the hypotenuse (side opposite right angle ) is equal to the sum of the squares on the other 2 sides.

Here x is thehypotenuse , then

x² = 36² + 77² = 1296 + 5929 = 7225 ( take square root of both sides )

`√(x^2)` =
`√(7225)` , then

x = 85
