If the sum of 7 and 9 is more than 12 add 3; if less, subtract 2. the correct answer is

The sum of 7 and 9 is:

7 + 9 = 16

The sum which is 16 is greater than 12. Therefore we add 3 to the sum:

16 + 3 = 19

Therefore the correct answer to this problem is 19.

54.864 meters

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
