3. Multiple Choice

Suppose someone donates a van at no charge.

Which equation represents the total expenses?

A. E= 125 + 30

B. E= 125n + 30n

C. E= 155

D. E= 155 +n

C

Step-by-step explanation: Since there are no additional charges, you would not need to add anything to your equation. (Unless there is information missing, then idk)

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
