Sam and his friends are playing in a slide in the city park. The slide’s ladder, which is perpendicular to the ground, measures 54 inches in height. If the base of the ladder is located 72 inches from the base of the slide, what is the length of the slide? A. 18 inches
B. 90 inches
C. 47. 7 inches
D. 126 inches

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
