Answer:

5) A = 70°

6) X = 55°

7) Y = 8°

8) A = 51°

Explanation:

There really no way to explain. All you ahve to do is inverse function to solve for the angle. Use a calculator.

5) sin(A) = 0.9397

$A=sin^-1(0.9397)\\\\A=69.701...\\\\A = 70\\$

6) cos(X) = 0.5763

$X=cos^-1(0.5763)\\\\X=54.998...\\\\X=55\\$

7) tan(Y) = 0.1405

$Y=tan^-1(0.1405)\\\\Y=7.997...\\\\Y = 8\\$

8) sin(A) = 0.7771

$A=sin^-1(0.7771)\\\\A=50.995...\\\\A = 51\\$
