Question 205921: The question: express theta as a function of X
A right triangle is shown with X as the adjacent and 7 as the hypotanus and a theta symbol at the bottom left angle.
What exactly is this question asking? Do I just need to solve the triangle?
Any help with this would be much appreciated. Thank you so much for your time.

The question: express theta as a function of X
A right triangle is shown with X as the adjacent and 7 as the hypotanus and a theta symbol at the bottom left angle.
-----------------
Since cos(theta) = adjacent/hypotenuse
So cos(theta) = x/7
-----------------------------
And finally theta = arccos(x/7)
