Omar Wants To Determine Cos Solved Measure The With Of A River He Marks Off Two

Omar can determine cos (θ) by using the reference angle of 30° and the information that cos (θ) is in the** fourth quadrant**. In the third quadrant, the cosine of an angle is negative because only the tangent and cotangent are positive. Use the reference angle of 30° and the fact.

Cos2(θ) = 1−sin2(θ) (taking the square.
