Do you have a graph or a picture? It would be easier to explain
Answer:
Option B
Step-by-step explanation:

Lets open the brackets of L.H.S.

Lets substract q² from both the sides.


Lets divide both the sides by q.


-2 is a solution because first you subtract 4x then after you get a new equation you move 15 to the left, then you subtract 15 from -1, then you factor the left side, then you divide both sides of the equation by 2
90 degrees plus 49 degrees is 139 degrees 180 degrees minus 139 degrees = 41 degrees
90+49=139
180-139= 41
answer 41 degrees
