1) Since the angle of the slide when it reaches the ground is supplementary we can state that:
2) Now we can use trigonometric functions to find the height of the slide, and length of the floor.
For the height of the slide
sin(25º)= y/3
0.422 = y/3 Multiplying by 3 on both sides
y=1.27 feet
3) Let's find the x, i.e. length of the floor
cos(25º) =x/3
0.906 = x/3
x=2.72 feet approximately
