Question

What is the length of PR?

Answer 1

Angle P and angle Q are the same, which means the two sides PR and QR are the same.

Set the two equations to equal and solve:

5n = 32 +n

Subtract 1n from each side:

4n = 32

Divide both sides by 4:

n = 32 / 4

n = 8

Now we have the value for n, solve for PR.

PR = 5n = 5(8) = 40
