After receiving a 25% discount, Sue paid $180 for a lawnmower. What is the original price of the lawnmower before the discount? Question 4 options:

$245

$225

$240

$220

$215

$240

Step-by-step explanation:

180 = original price - discount

180  =  OP  - OP x.25

180= OP(1-.25)

180 = OP x .75              divide both sides by 0.75

180/ .75  = OP

$240 = OP

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
