<span>Subtract 7 from both sides of the equation. Check: Substitute -4 for x in the original equation. If, after the substitution, the left side equals the right side, your answer is correct. ( -4 ) + 7 = 3 </span>

What is the correct answer?

Minchanka [31]

67.38 degrees

To find this, follow the steps below:

cos (B) = 5/13
cos -1 (cos(B)) = cos-1 (5/13)
The cos-1 and cos cancel each other out.

B = cos-1 (5/13)
B = 67.38

Hope this helps!
