Question

For the right angle shown, the length of two sides are given. Find the third side. Leave your answer in simplified, radical form.

b=9, c=16
a=

Answer 1

a is about 13.2

Explanation:

the formula for this type equation is a²+b²=c²

plug in the numbers to make the equation a²+9²=16²

do the multiplication and it gives u a²+81=256

subtract 81 from both sides and a²=175

take the square root of both sides and it gives u 13.22
