Solve for the unknown. Round decimals to hundredths and percents to the nearest tenth. If a number decreases from 88 to 33, what is the rate of decrease (as a %)?

c is the final : )

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

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
