Question

1) Jon is standing 60 feet from the base of a cliff watching a friend, Marvin, prepare to bungee jump. The angle of elevation to the top of the cliff is 73º. How high is the cliff Marvin is jumping from?​

Answer 1

196 feet

Explanation:

Let be A the point where Jon is standing, B the point at the base of the cliff and C the point where Marvin is standing, this situation resemble to a right triangle .AB us the distance from the base of the cliff, that is 60 feet.

m<BAC is 73° .We need to find BC.

Right angle is <ABC

tan73°=BC/AB

tan73°=x/60

x=tan73°*60=3.27*60=196 feet approximately.
