A circle measures 360°.
Since ∠DEF is equal to 70°, the rest of the circle will have a measure of 360 - 70 = 290°.
Central Angle and Arc relationship:
It states that the measure of the central angle and the arc that it intercepts are equal in measure.
Since ∠DEC is a central angle, its intercepted arc DF is also equal to 70°.
With this given facts, arc DGF is equal to 290°.
We can only solve for the degrees because radius is not given. Had it been given, the fraction 290°/360° will be multiplied to the circumference of the circle to get the length of the arc DGF.
Yup! Consider the circle:
r=cnt, for any angle. Impossible with (x,y), because for a given x, you need to y values. For a circle of radius 1, centered at the origin, y = +sqrt( 1-x^2) and y = -sqrt(1-x^2)
Also the spiral, etc ... Any hta has for one x value, two or more y values.

yup mhm oh yeah (its not in simplest form sorry)
(6n^2-4)+(-2n^2+9)
6n^2-4-2n^2+9
4n^2+5
Hope this helps!
