Critical value : 
margin of error : E= 1 mile per gallon
Population standard deviation:
miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by :

[Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37
The opposite angles of a quadrilateral are supplementary so you can set them equal to 180.
If there was more information given then i could find the exact values.
Hope this helps :)
