Question

Each leg of a 45°-45°-90° triangle measures 4 ft. What is the length of the hypotenuse?

Answer 1

The length of the hypotenuse is 5.66 ft

Explanation:

The triangle is a right isosceles triangle.

Both legs are 4 ft.

Use phytagorean theorem

c^2 = a^2 + b^2

c^2 = 4^2 + 4^2

c^2 = 16 + 16

c^2 = 32

c = √32

c = 5.656854

c = 5.66
