Tony. Please take some time to explain your answer in writing. Everyone is interested in how you arrived at your answer.

FIne, mr.j. follow the steps,
1) draw a line from that 20 degree angle to the 30 degrees one. Now it becomes an isoslate triangle.
and a small triangle inside

2)all we know an isoslate triangle is 180 degrees right? minus 40 from 180.

3) now the isoslate triangle's other 2 angles are 70 degrees right?

4) minus 20 degree in the left side, and minus 30 in the right side.

5) now the small triangle's 2 angles are 40 degrees and 50 degrees. What's the last angle.

Icewizard: 90 degrees?
Mr. Tony Zheng : right

and u left it obvious that ur ice wizard tony......-_-

Mr. J. Sorocco said...

I agree that the answer is 90 degrees. However, I don't agree that the triangle is isosceles.

I like the idea of drawing a line from Q to R forming triangle PRQ. As Tony states the sum of the angles in PRQ equal 180.

Let try explaining how to get this answer again without saying the PQR is isosceles. Tony ? Christine? Anyone else?
