It is given in the question that,
Line QS bisects angle PQR. Solve for x and find the measure of angle PQR.
And

Since QS bisects angle PQR, therefore

Substituting the values, we will get

Great Job! they are all correct. :)
Good luck in your next tests.

Answer: Choice A</h3>
The first line shown in choice A is
which means "the first term is -2"
The next line in choice A means "the nth term (
) is found by multiplying the prior term (
) by 8". Put another way: multiply each term by 8 to get the next term.
first term = -2
second term = 8*(first term) = 8*(-2) = -16
third term = 8*(second term) = 8*(-16) = -128
fourth term = 8*(third term) = 8*(-128) = -1024
and so on.
