This is the exterior angle theorem meaning the two angles in the triangle is equal to the outer angle of the angle. So you would set your equation to (3x+4) + 58 = 12+8x

Solve for x then plug the x back into the 12+8x equation to get your angle

Answer: x=6

Step-by-step explanation:

Let's solve your equation step-by-step.
