WebJul 12, 2024 · Use it to find cos(150 ∘) and sin(150 ∘). Solution 150 degrees is located in the second quadrant. It is 30 degrees short of the horizontal axis at 180 degrees, so the reference angle is 30 degrees. This tells us that 150 degrees has the same sine and cosine values as 30 degrees, except for sign. We know that sin(30 ∘) = 1 2 and cos(30 ∘) = √3 2. WebYou can enter input as either a decimal or as the adjacent over the hypotenuse.
