I would approach this question by changing the equations from polar to cartesian form. Do you know how to do that?
Answer:
A
Step-by-step explanation:
short cut, it has 5 dashes/ point markings
First, use triangle angle sum theorem on the triangle on the right.
180-(43+57)=80
Use vertical angles theorem,
the missing angle of the triangle on left is 80 as well.
Use triangle angle sum theory again.
2x+80=180,
x=50
So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6
