What is the length of PR?

Question

Answer:

So this is a common type of question. Don't overthink this, this is an isosceles triangle, meaning that the length of PR and QR are the same.

So set it up like this : 5n=32+n

Minus n on both sides, you get 4n=32

Divide by two on both sides, n=8

Now, PR= 5n so it would be 8*5

So the length of PR is 40 units
