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)

Best ResponseYou've already chosen the best response.0because of the 45º angle , the height of the short wall and the distance between the walls is the same 1. x = 230' / cos(45º) 2. y = x + [z * tan(20º)] 3. z = x

Best ResponseYou've already chosen the best response.0is there any more info given? i dont see how it is possible to find height of shorter wall (x) because all info is relative to the fixed point on the shorter wall.
