On the top problem: Angle A and Angle B are a right angle so it equals 90 degrees. If Angle B is 50 degrees that makes Angle A 40 degrees. Angle A and Angle C is a straight line and equals 180 degrees so if Angle A equals 40 degrees that means Angle C equals 140 degrees.
1. YX = 8√3/tan60° = 8
so ZX = ZY + YX = 10 + 8 = 18
2. angle Q
Answer:
A)
x= the number of ride tickets
y= the total cost of admission plus how many ride tickets a person purchases
B)
y= 1.25x + 9.5
C)
It is a$1.25 per ticket for the rides at the fair, so it would be 1.25 multiplied by the amount of tickets that are purchased (x). Spencer bought 17 tickets, so 17x1.25= 21.25 and it says that he spent a total of $30.75 at the fair, so 30.75-21.25=9.5, so that means the cost of admission is $9.50.

Step-by-step explanation:
3 + 4 + 5 + 6 + 6 + 7 + 8 + 8 + 9 + 9 / total of numbers or 10 = 65 ÷ 10 = 6.5 This is the mean.
3 - 6.5 = 3.5
4 - 6.5 = 2.5
5 - 6.5 = 1.5
6 - 6.5 = 0.5
6 - 6.5 = 0.5
7 - 6.5 = 0.5
8 - 0.5 = 7.5
8 - 0.5 = 7.5
9 - 0.5 = 8.5
9 - 0.5 = 8.5
MAD = 1.7
