a. These two angles form a straight line so their sum is 180 degrees.
2x + 3 + 132 = 180
2x + 135 = 180
2x = 45
x = 22.5 Supplemental angles

b. Angle d and exterior angle (131 degrees) form a straight line so their sum is 180 degrees.
131 + d = 180
d = 49 degrees Supplemental angles

90 + 49 + e = 180
139 + e = 180
e = 41 The sum of the measure of the angles of a triangle is 180

c. t = 19 + 24
t = 43 Exterior angle theorem
