Answer:
Approximately 83 degrees
Step-by-step explanation:
Consider the curve

Let us find equation of tangent or slope of tangent at (1,2)
Differentiate y wrt x

slope of tangent = value of derivative at that point
So slope of tangent at (1,2) = 
Slope of a line is nothing but tangent of the angle it makes with positive x axis
So if phi is the angle
we have

Approximately 83 degrees
