Answer:
6
Step-by-step explanation:
she spent 60 and she has 60 to spend so there 10 so she can buy 6
Remember that the total of the angles always equals 180 degrees
4x + 2 + 8 + 6x + 30 = 180
Now solve
4x + 2 - 2 + 8 + 6x + 30 = 180 - 2
4x + 8 - 8 + 6x + 30 = 178 - 8
4x + 6x + 30 - 30 = 170 - 30
4x + 6x = 140
10x = 140
10x ÷ 10 = 140 ÷ 10
x = 14
Now that we know what x is we can fill in the blanks
4(14) + 2
58 + 2
58
Angle O is 58 degrees
8 + 6(14)
8 + 84
92
Angle R is 92 degrees
To check we can add them all up
30 + 58 + 92 = 180
x = 14
both 7 and 14 can be divided evenly by 7
7/14 reduced to its lowest would be 1/2
