now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.
The sector of the circle formed by its two radius of length 12 inches has an area of 24 pi. This is obtained using the formula, Area is equal to the product of pi, radius squared and central angle all over 360.
