12
x = [ ?]
5
Enter your answer as a decimal rounded to the
nearest tenth

Answer 1

X=65.4°

`solution \\ cos \: x = (5)/(12) \\ x = {cos}^( - 1) (5)/(12) \\ x = 65.3756 \\ x = 65.4`

hope this helps..

Good luck on your assignment

Answer 2

x ≈ 65.4 °

Explanation:

cos x =
`(adjacent)/(hypotenuse)`

Cos x =
`(5)/(12)`

Cos x = 0.4167

x = Cos⁻¹ (0.1467)

x ≈ 65.4 °
