Homework Statement
A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.3 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 6 ft from the wall? Evaluate your answer numerically.
Homework Equations
a^2+b^2=c^2 ?
Theta(dot) is change of time respect to theta.
The Attempt at a Solution
In class he went over finding the rate of theta, getting the equation Theta(dot)=X/(10cos(45) I tried plugging in 6 for X, I just really don't know what to do here.
