Question 1036231: How would this problem be completed?
The three angles in a triangle measure 8b, b+20, and 40+3b.
I tried making them equal to 180 and solving for b, but I haven't been getting the answer my teacher gave us. I looked back in our notes, but he never showed us how to do it. The answers he gave are 30°, 70°, 80°.
Thank you!
