Question

Find the length of the missing side.

40 ft
75 ft
The length of the missing side is
ft.

Answer 1

85 ft

Explanation:

The Pythagorean theorem tells you the length of the hypotenuse (c) is related to the lengths of the legs (a, b) of a right triangle by ...

c^2 = a^2 +b^2

c^2 = (40 ft)^2 +(75 ft)^2 = 7225 ft^2

c = √(7225 ft^2) = 85 ft

The length of the missing side is 85 ft.
