A trampolinist jumps 60 inches in the air off a trampoline 2 inchies off the ground. The function h(t)=-16t^2+60,where t represents the time in seconds, h gives the geught, in inches, of the trampolinist above the ground as he falls. When will the trampolinist and land on the trampoline?

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
