I am assuming that the shape is a right triangle.
All interior angles of a triangle add up to 180°.
The missing angle should be 50°.
Hope this helps.
first polygon
ext. angle=180°-120°
=60°
n=360°/60°
n=6
second polygon
n=2(6)=12
ext. ang= 360°/n = 360°/12° = 30°
int. ang = 180°-30°= 150°
answer is C
