Step-by-step explanation:

(Angles in linear pair)



(Angle sum postulate of a triangle)



(corresponding angles)

(vertical angles)


Consider a function f(x), the linear approximation L(x) of f(x) is given by

Given the quantity:

We approximate the quantity using the function

, where x = 203.
We choose a = 200, thus the linear approximation is given as follows:
