Given that,
The area of a circle,
Central angle, = 330
We need to find the area of the sector. The formula for the area of sector is given by :
So, the area of the sector is equal to .
1. x = -5 or x = 3
You would add 16 to both sides. Then factor the left side and take a square root to solve.
2. x = -3 and x = -1
Use the same operations here only add 1 to both sides. <span />
It would be B. if that helps
