Type the correct answer in each box. Use numerals instead of words. If an answer for this question is not a whole number, enter it as a decimal. The expression 220.03 - (55.27 + 115.32) represents A. The expression 111.45 + (198.22 - 76.76) represents B. The expression 28.15 - 202.98 - 108.46 represents C.

A= 49.44

B= 232.91

C= -283.29 (unless there was supposed to be a parenthesis around 202.98 - 108.46 then it would be -66.37)

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
