The naming of parallelogram (or any other geometric figure) is conventionally clockwise or counter-clockwise.


So A and B are adjacent angles (which are supplementary)

=>

B=180-A=180-63=117 °


A and C are diagonally opposite, and are therefore congruent.

So

angle C = angle A = 63 °

allsm [11]
600 = 45x  (x= minutes) 
13.3333333=x 

1*(2/3) = 80 minutes 

80x= 13.333333*80
<span>
Therefore the airplane flies 1066.66664 km in 80 minutes or 1 2/3 hours
