Answer:b
Step-by-step explanation:i took the test its right i promise
First we need to establish the fact that angles on a straight line ALWYS add up to 180
So, we solve the equation for x which turns out to be 3
But,were not done. The question asks us to find the value of the angle BOC
so we substitute the value of x into the equation for BOC (which is 6x+29)
And then your answer is 47 degrees
The quickest way to get the series is if you already know the series for sine:

Then just multiply the series by
to get

The first four nonzero terms are simply the first four terms:
