X represents the amount of children's tickets
y represents the amount of adult's tickets
8(x+y) = 54
Answer:
y=7
Step-by-step explanation:
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
