Instead of x, we write n - 7 in the function equation

Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,



We know that, area of a sector is

Where,
is central angle, r is radius.




Multiply both sides by 360 degrees.


The value of x is 60 degrees.
Therefore, the correct option is A.
-9 × 3 - 4² = -27 - 16 = -43
3² + 2² = 9 + 4 = 13
(-9 × 3 - 4²)/(3² + 2²) = -43/13 = -3 4/13
