**4, 16, 30, 20, 10, 14****, ****and 26 are represented on a pie chart. Find the sum of the angles of the bisectors representing all numbers equals to or greater than 16**

**A.**** ****4****8 ^{o}**

**B.**** 84 ^{o}**

**C.**** 92 ^{o}**

**D.**** 276 ^{o}**

**QUICK ANSWER…**

**D**

**DETAILS…**

**If ****4, 16, 30, 20, 10, 14 and 26 are represented on a pie chart****,**** the sum of the angles of the bisectors representing all numbers equals to or greater than 16**** is 138.**

**Numbers equal or greater than 16 = 16, 30, 20, and 26**

**The sum of numbers equal or greater than 16 = 16 + 30 + 20 + 26 = 92**

**Sum of all the numbers = 4 + 16 + 30 + 20 + 10 + 14 + 26 = 120**

**The angle representing numbers that is equal or greater than 16 = 92/120 × 360**

**= 276⁰**

**The sum of the angle between the bisectors is also equal to 276⁰.**

**Now for the right answer to the above question:**

**Option A is incorrect.****Option B is not correct.****C is incorrect.****D is the correct answer.**

**KEY-POINTS…**

**You may please note these/this:**

**Angle formed by one of the numbers = (the number / sum of all the numbers) × 360****Sum of the angles of all the bisectors of the angles in a pie chart = sum of all the angles since it is formed within the circle.**
