Question

Cosines / Sines. PLEASE HELP ME AND PROVIDE A CLEAR ANSWER WITH EXPLANATION IF POSSIBLE

Answer 1

cos x = 9/17

x = 58.03 degrees

sin y = 9/17

y = 31.96 degrees

Answer 2

cos(x) = Adjacent leg / Hypotenuse

Adjacent leg = 9

Hypotenuse = 17

Cos(X) = 9 / 17

X = arccos(9/17)

X = 58.0 degrees
