Please help me on this Trigonometry Right Triangle question.
Two walls of a canyon form the walls 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 260 feet. Using the appropriate right triangle solving strategies, solve for the following: (Do not round intermediate calculated values. Only the final answer should be rounded to one decimal place.)
the height of the short wall (x)
the height of the tall wall (y)
the distance between the canyon walls (z)
x = ___ feet
y = ___ feet
z = ___ feet

Reason for asking: My reason for asking is because I have many questions like this on my homework sheet but the problem is I don't know how to answer them. I was/am hoping that someone would answer the question and go over the steps so that I can understand and try to use it in my other questions. I tried to use SOHCAHTOA but I'm not sure about it.
Thanks for the help.
