The sale price of an item on sale for 40% off is $48. what was the regular price?

Good evening ,

Step-by-step explanation:

Let p represent the regular price of the item.

p - p×(40/100) = 48 ⇌ p×(1 - 40/100) = 48 ⇌ p×(100/100 - 40/100) = 48

⇌ p×(60/100) = 48 ⇌ p = (480×100)/60 = 48 000/60 = 80.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

ok thats very interesting
