46.3°

Answer 1

43.1°

Explanation:

Hello, just finished the quiz and the correct answer is 43.1 degrees.

Answer 2

Answer: 43.1 degrees (choice B)

==================================================

Work Shown:

Use the law of sines

sin(A)/a = sin(C)/c

sin(A)/20 = sin(82)/29

sin(A) = 20*sin(82)/29

sin(A) = 0.68294349

A = arcsin(0.68294349)

A = 43.074088

A = 43.1 degrees
