Answer:
Step-by-step explanation:
since we can see that the lines are parallel
and we can see that the both are interior angles and when we sum up both angles we get 180
2x - 5 + 45 = 180
2x + 40 =180
2x = 180 - 40
2x =140
x = 140/2
x = 70
2?
2 is the square root of 4 since 2×2=4
$36
20x.80=16
20+16=36
Hence, the original price is $36
