Which step is the same in the construction of parallel lines and the construction of a perpendicular line through a point on the line? A. Create only one arc that intersects the original line. B. Create two arcs that intersect the original line. C. Place the compass on a point off the original line. D. Place the compass on a point on the original line. I will mark brainliest.

they are simplified

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
