An artist is using right triangles in her design. If all the triangles have an angle measure of 30°, what is the
measure of the third angle?
A) 150
B) 50
C) 60
D) 120

I think it’s C because a triangle is 180 degrees and it’s a right triangle which means there is a 90 degrees angle + 30 degrees.
90+30=120. 180-120=60
Which means the third angle is 60 degrees
