Answer:
13.2'
Step-by-step explanation:
zip line, tower n finish form right-angle triangle w/
zip line as hypothesis=20' n the distance to finish as one side=15'
the tower height^2 + 15^2 = 20^2
the tower height = sqrt (400-225)
=sqrt(175)
=13.2'
Answer:
Lucy has to climb 13.2 feet.
Step-by-step explanation:
By the Pythagoras theorem, with zip line being the hypothesis and the distance from tower base to finish as one side,
20^2 = 15^2 + Height^2
Height^2 = 400 - 225 = 175
Height = 13.22 feet
Lucy has to climb 13.2 feet.
