Answer:
Smaller angle: 69 degrees
Larger angle: 111 degrees
Step-by-step explanation:
Supplementary angles= two angles that make up 180 degrees
x = smaller angle
x + x + 42 = 180 Add like terms
2x + 42 = 180 Subtract 42 on both sides
2x = 138 Isolate the variable by dividing 2 on both sides
x = 69
x = smaller angle, 69 degrees
x + 42 = larger angle, 111 degrees
