Question

A hypotenuse of a 45 -45 -90 triangle measures 128cm what is the length of one leg of the triangle?

Answer 1

The square root of 128

Answer 2

Answer:

90.5cm

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

c= 128cm. c^2= 16384

a = b in 45-45-90

a^2 = b^2 = (c^2)/2 = 8192

√8192 = 90.51
