Step-by-step explanation:

As far as I know, the best way to solve this it to guess and check. You can make some logical inferences, for instance that you probably won't be dividing or multiplying 5 and 7, as the resulting number would either not be an integer or would be too large. Thinking like this, you can find that . Hope this helps!

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
