1st. Try to make x by itself. Divide 12 on each side.
After it will look like this
x=12
5x + 3. You can also synthetically divide because of the linear divisor
So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius

then use that radius in the circle's equation
Answer:
B=45
Step-by-step explanation:
let the supplamentary angle of <A is <d
180-A=d
180-135=d
45=d
90+d+B=180
90+45+B=180
135+B=180
B=180-135
B=45
