Answer:
$42.00
Step-by-step explanation:
20% OF 50 = 40
Before Tax Price: $40.00
Sale Tax: 5.00% or $2.00
After Tax Price: $42.00
First angle is x
x + (x + 45) + 2x = 180
4x + 45 = 180
4x = 180 - 45 = 135
x = 135 divided by 4
x = 33.75
first angle 33.75
second angle 78.75
third angle 67.5
checking
33.75 + 78.75 + 67.5 = 180

I'll say the question has no answer.
