Open the line segment reflection application. Line segment AB is a reflection of line segment CD across the x-axis. Click the reflect over x-axis button. Are line segments AB and CD the same? What does this mean about how a line segment changes when you reflect it?

answer: just subtact the units and then add the non negative : happy to

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
