First find the hypotenuse.
a^2 + b^2 = c^2
5^2 + 7^2 = c^2
c^2 = 25 + 49
c = sqrt(74)
sin(theta) = opp/hyp
sin(theta) = 7/(sqrt(74))
STEP 1:
Discount $= Price times discount %
=$5.00 * 50%
=$5.00 * 0.50
=$2.50 discount amount
STEP 2:
Sale price= Original $ - Discount amount
=$5.00 - $2.50
=$2.50 sale price
ANSWER: Discount amount is $2.50 and the sale price is also $2.50.
