Answer:
360
Step-by-step explanation:
All circles can be divided into 360 units called degrees. Since there is 270 already we subtract 270 from 360.
360 - 270 = 90
90 + 150 + 120 = 360
To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

Equation of a circle:
The equation of a circle with center
and radius r is given by:

Center at (16, 30)
This means that 
Thus

Passes through the origin:
We use this to find the radius squared, as this means that
is part of the circle. Thus



Thus, the equation of the circle is:

Could it be Red Blue Blue Green Purple? Or Red Blue Green Grey Purple?
Answer:
Step-by-step explanation:
5x-2y=24
x+2y=12
add the two equations
(5x-2y)+(x+2y)=24+12
6x=36
x=6
Plug in x=6 into any of the two equations
5(6)-2y=24
30-2y=24
-6= -2y
y= 3
x=6
y=3
(6,3)
