The question
tan A =
Write tan A as a fraction
How it works.
tan A=opposite / adjacent
tan A=
tan A=
- 01
tan A is opposite over adjacent. Name the two sides you need, measured from angle A.
- 02
Read them off the triangle: the opposite side of angle A is 9, the adjacent is 40.
- 03
So tan A = 9/40.
