Santana says the image is formed from the pre-image by a reflection across the y-axis followed by a translation 2 units to the right, in that order. is santana’s thinking correct?

No. From how I see it, it appears that it would be a translation 2 units to the LEFT.

gdp is the best phrase!

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
