<h3>
Answer:</h3>
[5] <u>By central angle property</u>,
- x = 6x - 290
- x - 6x = - 290
- - 5x = - 290
- x = 290/5
- x = 58.
[6] <u>By same arc property</u>,
- 8x + 4 = 9x - 11
- 8x - 9x = - 11 - 4
- - x = - 15
- x = 15.
[7] <u>By central angle property</u>,
- 7x + 4 = 2x + 49
- 7x - 2x = 49 - 4
- 5x = 45
- x = 45/5 = 9.
[8] <u>As they are radius i.e, equal</u>,
- x + 9 = 2x + 6
- x - 2x = 6 - 9
- - x = - 3
- x = 3.
[9] <u>By central angle property</u>,
- 9x = 12x - 21
- 9x - 12x = - 21
- - 3x = - 21
- x = - 21/- 3
- x = 7.
[10] <u>They are radius so equal</u>,
- 8x + 2 = 10x - 20
- 8x - 10x = - 20 - 2
- - 2x = - 22
- x = -22/-2
- x = 11.
The answer is going to be D
He answer is 21. 94 was the largest value and 73 was the smallest. When you subtract them you get 21.
