Three of four numbers have a sum of 22. If the average of the four numbers is 8, what is the fourth number? a) 4 b) 6 c) 8 d) 10
kogti [31]

Answer:

10

Step-by-step explanation:

First you do 8 × 4, this gives the total of the four numbers.

8 \times 4 = 32

Then, subtract the total of 3 of the numbers from the total of 4 of the numbers.

14. A polygon ABCD is inscribed in a circle. Find angle ABC
andreyandreev [35.5K]

Answer:

m<ABC = 100degrees

m<IJG = 104degrees

Step-by-step explanation:

14. The sum of the opposite angle of the quadrilateral is 180degrees. Hence;

m<ADC + m<ABC = 180

3y+8+4y+4 = 180

7y + 12 = 180

7y = 180 - 12

7y = 168

y = 168/7

y = 24

Get <ABC

m<ABC  = 4y+4

m<ABC = 4(24) + 4

m<ABC = 96 + 4

m<ABC = 100degrees

15. Similarly for this;

GHI + IJG = 180

76 + m<IJG = 180

m<IJG = 180 - 76

m<IJG = 104degrees
