Answer:
4
Step-by-step explanation:
To find the value of g(7), locate 7 on the x-axis. Follow the grid line upward until it meets the graph (blue line). At that point, follow the grid line to the left until it meets the y-axis. Read the value from the scale on the y-axis.
g(7) = 4
Since X : Y = 1 : 2, X = 0.5Y.
Since Y : Z = 2 : 5, Z = 2.5Y.
We have X + Y + Z = 4Y = 40. Hence Y = 10.
130° degrees
semi circle = 180°
so 13/18 of 180° = 130°
x=-15/2 , 4
I'm sorry if I'm wrong
