For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the equation that models the problem:

From here, we clear the value of x.
We multiply both sides of the equation by 2:

We subtract 30 on both sides of the equation:

Answer:
The value of the unknown number is given by:

Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
First one is y=4x and the second one is y=2x
