For a motorcycle stunt the end of a 45 meter ramp must be 32

For a motorcycle stunt. the end of a 45 meter ramp must be 32 meters above the ground, what angle of elevation should the ramp have?

let the angle of elevation be \'x\'

then tan(x) = 32/45

tan(x) = 0.711

x = 35.4 degree

so the angle of eleveation is 35.4 degree

2).

tan(90 - 36) = 350 /h

tan(54) = 350/h

h =350/tan(54)

h=254.3 feet

10). tan(37) = h /135

h = 135 /tan(37)

h =179.15 feet
