Instructions:
Find the measure of each angle. Calculate the Length of each side.

Answer 1

A = 38.7° , B=51.3°

Explanation:

Solve for degree B.

tan(B) = Opp/Adj

tan(B) = B/A

B = tan^-1(15/12)

B = 52.8°

Two options to solve for degree A.

180° - 90° - B° = A°

A = 38.7°

Or

A = tan^-1 (11.4/15)

A = 38.7°
