Question

Find the value of x and round angles to the nearest whole degree

Answer 1

`\cos(x) = (4)/(6) \\ \cos(x) =(0.66666666667)\\ x = { \cos (0.66666666667) }^( - 1) \\ x = (48.18968510422)`

Answer 2

48

Explanation:

This is a simple Trigonometry problem

cos(x) = 4/6

cos^-1(4/6) = 48.18 = 48
