Answer:
Step-by-step explanation:
I believe is D because you actually change the measure of two angles as long as the sum of them are 90.
Answer:
i would say b
Step-by-step explanation: if they all slept 4 hours a night then all 9 would have a total of 36 and a night would be 1 so 36 to 1
Part A)
vertical angles are equal so
3x - 8 = 2x+12
x = 20
3(20) - 8 = 60 - 8 = 52
part B)
straight angle = 180
so
52 + y = 180
y = 180 - 52
y = 128
