((7-5) 2 divided 2) times (3+4+10)

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

step-by-step explanation:

any linear relation with finite slope (that is, something other than x=constant) will be a function with a domain and range of "all real numbers."

further, any odd-degree polynomial will likewise be a function with domain and range of "all real numbers." a linear equation is a polynomial of degree 1, hence of odd degree.
