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.

Answer:
<h2>
2x²+x-3</h2>
Step-by-step explanation:
Given the expression (2x⁴ – 3x² + 7x - 3) ÷ (x² - 2x + 1), we are to use the long division method as shown in the attachment below.
The quotient on dividing is 2x²+x-3
