Question

Use the triangle below and the given trigonometric ratio to determine which angle in the triangle below is

Answer 1

Answer: Angle 2

The 7.5 cm side is opposite angle 2, so opposite = 7.5
The 18 cm side is adjacent to angle 2, so adjacent = 18

Therefore, tan(angle 2) = opposite/adjacent = 7.5/18
Replace "angle 2" with "A" and we have tan(A) = 7.5/18
