step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation
