$277 - 252 \cos (180 - x) = (244 - (240 \cos (x)))$

Step 1

Remove parentheses.

$277 - 252 \cos (180 - x) = 244 - (240 \cos (x))$

Step 2

Multiply $240$ by $- 1$ .

$277 - 252 \cos (180 - x) = 244 - 240 \cos (x)$

Step 3

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx 2.12272069 + 2 π n, 5.11413106 + 2 π n$ , for any integer $n$
