Step-by-step explanation:

Using a calculator :

sin(A) = 0.9903

A = sin^-1(0.9903) = 82.01 = 82°

6.) cos(A) = 0.6428

A = cos^-1(0.6428) = 49.99 = 50°

8.) tan(A) = 1.2851

A = tan^-1(1.2851) = 52.111 = 52°

9.) cos(A) = 1.2608

A = cos^-1(1.2608) = domain error

10.) sin(A) = 0.7777

A = sin^-1(0.777) = 50.98 = 51°

11.) sin(A) = 1.8330

A = sin^-1(1.8330) = domain error
