Two walls of a canyon form the sides of a steady flowing river. From a point on the shorter wall, the angle of elevation to the top of the opposing wall is 20° and the angle of depression to the bottom of the opposing wall is 45°. From the same point, the diagonal distance to the bottom of the opposing wall is 230 feet. Using the appropriate right triangle solving strategies, solve for:
1. the height of the short wall (x)
2. the height of the tall wall (y)
3. the distance between the canyon walls (z)

Question

Two walls of a canyon form the sides of a steady flowing river. From a point on the shorter wall, the angle of elevation to the top of the opposing wall is 20° and the angle of depression to the bottom of the opposing wall is 45°. From the same point, the diagonal distance to the bottom of the opposing wall is 230 feet. Using the appropriate right triangle solving strategies, solve for:
1.	the height of the short wall (x)
2.	the height of the tall wall (y)
3.	the distance between the canyon walls (z)
