Question

Confused.

Answer 1

I have a diagram.

Answer 2

@AriPotta Are you available for help?

Answer 3

If you have a diameter and use that as one side of the triangle, what's special about the angle opposite the diameter?

Answer 4

Which angle?

Answer 5

Say, PRM.

Answer 6

It's right

Answer 7

I mean it's a right angle....

Answer 8

We can start by finding a way of proving that QR = PR using angles, because that's probably the way to go. So what do you think?

Answer 9

Well....PMR is about 25 degres.

Answer 10

So.....RPM is 65.

Answer 11

How did you get PMR is around 25 degrees?

Answer 12

Protractor.

Answer 13

Lol nice! But then it'll change if Q changes, right? since Q can be any point on the circle apart from M & P.

Answer 14

Correct.

Answer 15

OH I GET IT NOW. :)

Answer 16
