SUM OF THE INTERIOR ANGLES OF A TRIANGLE #2
Directions: Solve for x in each of the triangles below. The Triangle Sum Theorem states that the interior angles of a
triangle always add up to 180. Your first step should be to set up an equation where the sum of the angles adds up to
180. Solve the equation for x, then plug that value back in to the expressions to find the measure of the missing angles.
