Answer:
77 degrees
Step-by-step explanation:
The angles of a triangle must add up to 180 degrees
61+42=103
180-103=77
77
I always add up the other two and since the total degrees of a triangle has to add up to 180 I subtract the sum so
180 - 103 = 77

Luis: x+4
x+x+4=52
2x+4=52
2x=48
x=24: Colleen
x+4=28 Luis
