Answer:
5. the other angle has to be 2x because of the other lines being equals so
2x+2x+x-15=180
5x-15=180
5x=195
x=19
6. the other two angle is ajacent to the other two so
3x+17+3x+17+x-9+x-9=360
8x+16=360
8x=344
x=43
7. this ones pretty simple
2x-4+3x+5+2x+11=180
7x+12=180
7x=168
x=24
8. this one to
x+x+4+3x-9=90
5x+5=90
5x=85
x=17
Hope This Helps!!!

Answer:

Step-by-step explanation:
The general equation for a circle is

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
The standard form would be x+3y=-27
