Find the measure of the exterior angle

133°

Step-by-step explanation:

Exterior Angle Theorem states that the sum of the two remote interior angles is equal to the exterior angle of the triangle.

Step 1: Combine like terms.

Step 2: Subtract x from both sides.

Step 3: Subtract 13 from both sides.

Step 4: Divide both sides by 2.

Step 5: Plug in 40 in 3x + 13.

Therefore, the answer is 133°.
