Answer:
m∠1= 80
m∠2= 100
m∠3= 80
Step-by-step explanation:
Given: m∠1= 2x +40
m∠2= 2y +40
m∠3= x +2y
m∠1 +m∠2= 180 (adj. ∠s on a str. line)
2x +40 +2y +40= 180
2x +2y+ 80= 180
2x +2y= 180 -80
2x +2y= 100
2(x +y)= 100
x +y= 100 ÷2
x +y= 50 -----(1)
m∠1= m∠3 (vert. opp. ∠s)
2x +40= x +2y
2x -x +40= 2y
x= 2y -40 -----(2)
Substitute equation (2) into (1):
2y -40 +y= 50
3y= 50 +40
3y= 90
y= 90 ÷3
y= 30
Substitute y= 30 into equation (2):
x= 2(30) -40
x= 60 -40
x= 20
m∠1
= 2x +40
= 2(20) +40
= 40 +40
= 80
m∠2
= 2y +40
= 2(30) +40
= 60 +40
= 100
m∠3
= x +2y
= 20 +2(30)
= 20 +60
= 80
Alternatively, since m∠1= m∠3,
m∠3
= m∠1 (vert. opp. ∠s)
= 80

Answer: the regular price is $6.5 each.
Step-by-step explanation:
Let x represent the regular price of a ticket to a basketball tournament.
Discount tickets to a basketball tournament sell for $4.00 each. Sam spent $60.00 on discount tickets. This means that the number of tickets that Sam bought is
60/4 = 15 tickets
The cost of 15 tickets at the regular price is 15x
Since the amount he paid is $37.5 lesser than what he would have paid if he bought the tickets at the regular price, then
15x = 60 + 37.5 = 97.5
x = 97.5/15
x = 6.5
