Question

Geometry help

Answer 1

A.

Answer 2

tan = TOA = \[\frac{ opposite }{ adjacent }\]

Answer 3

So you won't use 25 anywhere in the answer because it is the hypotenuse. The hypotenuse is only used for sin and cos
sin = SOH = \[\frac{ opposite }{ hypotenuse }\]
cos = CAH = \[\frac{ adjacent }{ hypotenuse }\]
