Textbook Problem

In △ A B C ,   m ∠ C = 90 ° . Use a square root radical to represent:a) c, if a = 5   a n d   b = 4 b) a, if b = 6   a n d   c = 8 To determine

a)

To find:

The value of c.

Explanation

Given, In ABC,mC=90°

a=5 and b=4 (Legs)

C is the hypotenuse.

By Pythagorean Theorem,

The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the length of the legs.

c2=a2+b2<

To determine

b)

To find:

The value of a.
