The angle measure of each unknown angle is 28° and 79°.
Using the information given, we can make the equation:
(x-5) + (3x) = 107
Combine like terms:
4x - 5 = 107
Add 5 to each side:
4x = 112
Divide each side by 4:
x = 28
Therefore, the measures of the two unknown angles are:
x - 5 = 28 - 5 = 23°
3x = 3*28 = 84°
So the angle measures of the two unknown angles are 23° and 84°.
