Since the discount is 20%, we know that $24 is 80% or 4/5 of the original price of the shoes. Divide the $24 by 20%, and you get $6. Add that to $24, and you get the original shoe price: $30. You can verify by Multiply 30 by 80%, which comes out to the discount price-$24.

Step-by-step explanation:
Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is 
x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 = (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
