We know that a circle is equal to 360 degrees. 

Each of the sections in the pie chart has coefficients/variable/number that would all equal to 360 degrees because they are part of the circle
Transportation - x
Books - 14.4 
Board - 1.6x
Room - 2x
Tuition - (since it is 50% we know that the coefficient that would represent this is 5x. also note how for, as an example, the room--since it consumes 20% of the circle--equals to 2x, we can state that 50% can be 5x)  

so
 $x + 14.4 + 1.6x + 2x + 5x = 360$

find out what x is equal to and once you get that see what we need to do to find the degree of the room (2x) and plug the value of x where x belongs in 2x to get your answer.
