WebMay 16, 2024 · Explanation: First of all, observe that 150 = 180 −30. Then, remember that we have cos(180 − x) = − cos(x) sin(180 − x) = sin(x) Plug in x = 30 to get cos(180 − 30) = −cos(30) sin(180 − 30) = sin(30) the answer comes from the fact that cos(30) = √3 2 and sin(30) = 1 2 are known values.
