Question 54924
One angle of a triangle has a measure of 70 degrees. The other two angles have degree measures in a ratio of 5 to 6. What is the sum of the measures, in degrees, of the two largest angles? 
I first tried 50 +60=110+70=180. 
ONE ANGLE =70
HENCE SUM OF OTHER 2 ANGLES = 180-70=110...YOU ARE CORRECT!WHY DOUBT?
SINCE ANGLES ARE IN 5:6 RATIO...TAKE THEM AS 5X,6X
5X+6X=11X=110...HENCE X=110/11=10
SO THE 2 ANGLES ARE 50,60..

Then I realized that 180 is the sum of all of the angles in a triangle, so it couldn't be right.
WHY IT IS RIGHT ..SUM OF 3 ANGLES 50,60,70 IS 180
 Thanks if you can help!
