Step-by-step explanation:
The sale price is the difference between original price and discount.
The discount can be calculated by taking 20% of original price.
Discount=20% of original price= (20/100)*50=0.2*50=10
Discount=$10
Sale price=Original price - Discount price
Sale price=50-10=40
Sale price=$40
The sale price of a jacket is $40.
cos (angle) = adjacent leg / hypotenuse
cos (50) = 6 / x
x = 6 / cos(50)
x = 9.3
