Answer:
128°
Explanation:
1 = 4 because of vertical angles are the same
4 = 5 because of alternate interior angles are the same
5 = 8 vertical angles
8 = 9 alternate interior angles
9 = 12 vertical angles
180° = 12 + 11
11 = 180° - 52°
angle 11 = 128°

This question confused the heck out of me, but I tried my hardest. Here you go:
Step-by-step explanation:
I solved the problem with sin and cos and all that, and I got 2.81859485365.
When I divided pi by 2, I got 1.57079632679
. So basically, the problem that was supposed to show that 0<C<pi/2 is correct is incorrect. Does that make sense? If not, just ask in the comments, and I'll edit this answer.
