Question

A right triangle has a hypotenuse of 153 centimeters and a leg of 72 centimeters. What is the length of the other leg? 135 centimeters 134 centimeters 135 meters 174 centimeters

Answer 1

You need to use the pythagorean theorem.

So...
a^2 + b^2 = c^2
72^2 + b^2 = 153^2
5184 + b^2 = 23409
b^2 = 18225
b = 135

A) 135 cm

Answer 2

a^2 + b^2 = c^2....where a and b are the legs and c is the hypotenuse
72^2 + b^2 = 153^2
5184 + b^2 = 23409
b^2 = 23409 - 5184
b^2 = 18225
b = sqrt 18225
b = 135 cm <==
