Question

Question 7 options:

A right triangle has a hypotenuse that is 15 centimeters. The length of one of the legs is 10 centimeters.

The length of the other leg, rounded to the nearest tenth, is ___ centimeters.

Answer 1

a^2 + b^2 = c^2

10^2 + b^2 = 15^2

100 + b^2 = 225

b^2 = 225 - 100

b^2 = 125

b = square root 125

b = 11.2cm
