To find arc WY:
360 - 156 - 86
arc WY = 118
To find angle WXY
118 / 2 = 59 degrees
8217 I think but I'm not sure
Equation: 0.5x + 8.3
Plug in 12 for x and solve
Step-by-step explanation:
The given numbers are : 32 , 48 , 140 , 120
First number is 32
Second number is 48
Third number is 140
Fourth number is 120
First number/second number :

Third number/Fouth number :

From equation (1) and (2) we can see that the ratio is not same. Hence, they are not in proportion.
