Answer:
Step-by-step explanation:
a + 143 = 180 {Linear pair}
a = 180 - 143
a = 37
37 + 93 + b = 180 {Angle sum property of triangle}
130 + b = 180
b = 180 - 130
b = 40
c + b = 90
c + 40 = 90
c = 90 - 40
c = 50
d + 120 = 180 {Linear pair}
d = 180 - 120
d = 60
? = 60 + 40 {Exterior angle property of triangle}
? = 100
Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70
