Find the measure of the indicated angle to the nearest degree. show me how to do.

74) Use inverse sine, sin⁻¹ because you are trying to find the measure of the         angle, x, and you are given opposite and hypotenuse.
       sin⁻¹(35/57) = 52.1182
D) 38°
75) Use inverse tangent, tan⁻¹ because you are given opposite and adjacent.
       tan⁻¹(20/26) = 37.5686
C) 38°

76) Use inverse sine because you are given opposite and hypotenuse.
       sin⁻¹(7/11) = 39.5212
D) 40°

77) Use inverse tangent because you are given opposite and adjacent.
       tan⁻¹(4/14) = 15.9454
D) 16°

Ithink it is 7. 16
