Relative to angle A, this is how the sides of a right triangle would be labeled. |
The tangent of angle A equals the length of the opposite side divided by the length of the adjacent side.
We could write:
tan(A) = opp / adj
So, for example, if the length of the opposite side was 6 and the length of the adjacent side was 8, then we would write:
tan(A) = 6 / 8
tan(A) = 0.7500
