Question

Find the length of the missing side.

The length of the missing side is​

Answer 1

85

Explanation:

The most obvious way to solve this is by using the Pythogream therom which I strongly reccomend learning.

`a^(2) + b^(2) = c^(2)`

Answer 2

85 ft

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let h be the hypotenuse, then

h² = 40² + 75² = 1600 + 5625 = 7225 ( take the square root of both sides )

h =
`√(7225)` = 85
