Domain is always and reads
range is always and reads

Domain: The set of possible input values to a function

Range: The set of possible output values of a function

Step-by-step explanation:

The domain of a function is the complete set of possible values of the independent variable

The Range is the difference between the lowest and highest values

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
