Question

Rewrite the following expression as the tangent of an angle.
tan23 + tan55/1-(tan23)(tan55)

Answer 1

Please clarify your expression. We don't know if you mean tan(23) + (tan(55))/(1-tan(23)tan(55)) or something else.

Answer 2

The sum formula, tan (x+y) = tan(x) + tan (y) all divided by 1 - tan (x) tan(y)

So your expression is the formula for tan (x+y) where x = 23 and y = 55

So, final answer; tan (78)
