Answer:
48°
Step-by-step explanation:
We can use the explanations from my previous answers to solve this. Lines are 180 degree angles. Use the equation: x + 132 = 180
Solve that:
180 - 132 = 48
a. Recall that

For
, we have

By integrating both sides, we get

If
, then

so that

We can shift the index to simplify the sum slightly.

b. The power series for
can be obtained simply by multiplying both sides of the series above by
.

c. We have
