Hope this helped you out.
Since f and g are parallel to eachother, the sum of the angle 7x and 2x+36 would equal 180. To solve for x, you add 7x+2x+36, set it equal to 180, and then solve for x.
x= 16
x = 36.2 .

Explanation:
________________________________________________
2x - 1 + 3x = 180 ;
Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .

Answer:
Step-by-step explanation:
In writing equations for circles with the center and radius given we follow the formula 
.
The value of h and k are the center values of (0,0).
So we have:
h = 0
k = 0
r = 4
Now let's plug these values into our formula.
