We are looking to figure out the size of m<CAB
Since line AB is parallel to the line CD, m<CAB corresponds to m<ECD which means the size of the angles equals
m<ECD can be found by using the fact that angles in a triangle add up to 180°,
hence, 180°-58°-43°=79°

The size of m<CAB is 79°

The answer would be about 98 hamburgers.
This is because you would have to divide 393 by 2 to get 196.5.
Since the number of cheeseburgers is doubled divide 196.5 by 2 to get 98.25.
Add 98.25 to 196.5 and get 294.75.
Subtract.
