If the exterior angle drawn measures 180°, and the measure of angleD is three times that of angleE, find the measure of the two remote interior angles.

#3 would be D because you have to take the total amount of hours (h) and subtract either 1/2 or 3/4 because those are the two times and whichever one you pick your answer will be the other one. 
#4 would be C because if you change the denominators to fourths then you will realize it is 3/4 of an hour plus 2/4 of an hour and that equals 5/4 which is also one and one fouth
