Question

How do you find the complement and supplement of `(3pi)/4`?

Answer 1

Complementary angles add up to `pi/2` aka `90^\circ` so the complement of `frac{3pi}{4}` is `pi/2 - frac{3pi}{4}= -pi/4`. Supplementary angles add to `pi` aka `180^\circ` so the supplement of `frac{3pi}{4}` is `pi - frac{3pi}{4 } = pi/4`.
