The sum of three consecutive integers is 9.

2

Step-by-step explanation:

because they're consecutive, each integer has to come right after the one before it.

if 1st integer is 1, the 2nd should be 2, and the 3rd should be 3.

3 is equal to 1 + 2, or n + 2

hopefully that works

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

4+4+2x

or

2x+8
