Answer:
2.05
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between sides of a right triangle and trig functions. Since you want the tangent, you are interested in ...
Tan = Opposite/Adjacent
The side opposite angle C is ED=80. The side adjacent to angle C is CD=39. Then the tangent is ...
tan(C) = ED/CD = 80/39
tan(C) ≈ 2.05
