Angle 1 = 52°
Angle 2 = ∠1 = 52 ° (isosceles triangle)
Angle 3 = 180° - 2∠1 = 180° - 2(52°) = 76°
Angle 4 = ∠3 = 76° (vertical angles)
Angle 5 = 180° - 2∠4 = 180° - 2(76°) = 28°
Angle 6 = ∠4 + ∠5 = 76° + 28° = 104° (exterior angle)
Angle 7 = 180° - 2(180° - 104°) = 180° - 2(76°) = 28°
Angle 8 = ∠6 = 104° (exterior angle)

Step-by-step explanation:
Really nice problem
<1 = 52 Given
<2= 52 The triangle is isosceles. Angles are equal because they are opposite equal sides.
<3 = 180 - <1 - <2 = 180 - 2*52
<3= 180-104 = 76 Every triangle = 180 degrees.
<4 = 76 Vertically opposite angles (which are equal)
<5 = 180 - 2*76 = 28 180 - 2 base angles (76) taken away from 180
<6 = 76+28 = 104 The exterior angle equals <4 + <5
<7 = 180 - 2*Supplementary angle to <6 180 - 2*76 = 28
<8 = <7 + <4 = 28 + 76 = 104
See if you can figure out why I used angle 4

The answer is C aka y = -4x + 42 and the number of complaints are 28!

I hope this helped, I did the same test and I'm sorry if its wrong :(
