To find the measure of angle 1, you add 33 and 57
That would equal 90
Since all triangles equal 180, you would subtract 90 from 180
So the answer would be 90.

Savatey [412]
500 = 200 + 20h is our equation.
Subtract 200 from both sides
300 = 20h
Divide by 20
300/20 = 15.
It will take 15 hours to get 500 points.
Hope this helps!
