Y= 18 because vertical angles are congruent.
The answer is 400 + .04. Or if you want a big answer, then it would be. 400 + 00 + 0 + .0 + .04.
For this case we have the following functions:

The first thing we must do for this case is to subtract both functions.
We have then:

Substituting we have:

Rewriting we have:

Evaluating the obtained function for x = 3 we have:

Answer:
The value of the function evaluated at x = 3 is:

Answer:
0.5%
