It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.
Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.
y+30=3y-50
-2y+30=-50
-2y=-80
y = 40
C)40.
Answer:
40%
Step-by-step explanation:
18/45 × 100
2/5 × 100
40%
Let the year represents x axis and consumption represents y axis.
Since 2010 is the initial year, x=0
and 2013 is third year , so x=3
Co-ordinates are (0,8.938)(3,10.480)
Exponential formula is 
Putting the value of x in the above formula from 1st coordinate,

As
= 1
this gives a= 8.938
Now using the 2nd coordinate

putting the value of a in it we have

taking cube roots on both sides we get
b= 1.05448
Now putting the values of a and b in the exponential formula-

In the year 2028, x=28
so,

y= 39.474
Hence oil consumption per day in 2028 will be 39.474 million barrels.
