The function f(c) = 9/5 c+32 allows you to convert degrees celsius to degrees
fahrenheit. find the inverse of the function so that you can convert degrees
fahrenheit back to degrees celsius.

the square root of what number? if you add that, then someone will probably answer the question.

900 degrees

step-by-step explanation:

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

using pemdas, (order of operations) you'll see the answer is 24.
