Answer:

75.96^o

Explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

tan(A)=(BC)/(AC) ----> by TOA (opposite side divided by the adjacent side)

substitute the given values

tan(A)=(80)/(20)

using a calculator

$m\angle A=tan^(-1)((80)/(20))=75.96^o$
