The biggest attraction at the new amusement park, World of Fun, is the huge slide that goes under the ground. To get to the top of the slide, Jon has to climb up a 56foot ladder. Then he rides the slide to the bottom. Finally, Jon walks through a tunnel to the elevator and rides a 35 feet to get back to ground level. The section of the slide that is above ground level is 77 feet long.
a) Use the similar triangles to find the length of the portion of the slide below ground level.
b) What is the total length of the slide.

Hint:
x/35 = 77/56 etc.
Let me know what you got
