Line segments ab and cd are both part of the same non–vertical line, and the slope of line segment ab is 4. using similar triangles, what can you show the slope of line segment cd to be?

∠cbe and ∠deb are same-side interior angles.

i took the test

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
