Question

Please explain to me how you get y and what y is for both problems

Thank you appreciate it !

Answer 1

4.

cos (angle) = Adjacent leg / hypotenuse

Cos(30) = Y / 16

Y = 16 * cos(30)

Y = 8√3

5.

cos(angle) = Adjacent Leg / hypotenuse

cos(Y) = 55/75

y = Arccos(55/75)

Y = 42.833 degrees. (Round answer as needed)
