Use the inverse of the tangent ratio to find the approximate measure of the missing angle. Round your answer to the nearest whole degree. 2cm and 5cm
To find the missing angle, we will use the inverse tangent ratio, which is arctan.
The tangent of an angle is equal to the opposite side over the adjacent side. In this case, the opposite side is 2cm and the adjacent side is 5cm.
tan(θ) = opposite/adjacent
tan(θ) = 2/5
To find the angle θ, we take the inverse tangent of 2/5:
θ = arctan(2/5)
θ ≈ 21 degrees
Therefore, the approximate measure of the missing angle is 21 degrees.
