Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21

The third angle is 20°. This is because you add the two angles you have already (95+65) and then you subtract that from 180. In simplier words: If you know 2 angles then you can subtract their sum from 180° to find the measure of the 3rd angle.
