Explanation:
Straight angles are always 180 degrees in measure.
The two smaller angles shown add up to 180
(angle RQS) + (angle SQT) = angle RQT
(9x+7) + (6x+8) = 180
(9x+6x) + (7+8) = 180
15x+15 = 180
15x = 180-15
15x = 165
x = 165/15
x = 11
From here, we then know that,
Note how the two results add to 106+74 = 180 to help confirm the answers.

B its 4 7/8 --------------
#1-List all outcomes for choosing the digit. *
0)
O
A: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
B: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
C: 1, 2, 3, 4, 5, 6, 7, 8, 9
OD: a number
Both B and C
a+b+c = 180
48+59+b=180
107+b=180
b=180-107
b=73
