Answer: 63
Explanation:
First we would need to find measure of angle 3. We can find this by setting up the equation 31 + 32 + x = 180, where x is the measure of angle 3.
We would set the 3 angles in the triangle to 180 since all the angles in a triangle add up to 180 degrees.
Solving for x, we get 117.
Since angles 3 and 4 are supplementary angles (angles that add up to 180 degrees), we can solve for angle 4 with this equation: 117 + y = 180, where y is the measure of angle 4. Solving for y, we get 63.
