Question 1161789
<font face="Times New Roman" size="+2">


Take the first derivative of the function.  Evaluate the function at the zero of the function giving the slope of the tangent line at the x-intercept.  The acute angle formed by the tangent line at the intercept is the acute angle formed by the curve at that point.  The measure of the angle is the inverse tangent of the slope of the tangent line.
