The task represents triangle with 90 degrees angle bellow top of the waterslide. that means that we can yous trigonometry functions to find out all the angles or lengths of triangle.
In this case we need to find height which we will find using tan function. tan(13) = x/58.2 x = 58.2*tan(13) = 13.43m
Rotating a figure 90° counterclockwise about the origin results in an ordered pair (x, y) mapping to its image (-y, x). Thus point C, which is at (3, 5), will map to (-5, 3).
