Step-by-step explanation:
If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special 
triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,
By the Pythagorean theorem,
F(2) = 20(1.25)^x
f(2) = 20(1.25)^2 - plug in 2 to x
f(2) = 20(1.5625) - calculate 1.25^2
f(2) = 31.25 - simplify
