Question 419460
 Find the measures of the angles in a triangle if the ratio of the measures of the three angles is 13:16:21. 
----------------------------------
13:16:21 is the same as 13x:16x:21x
----
Equation:
13x + 16x + 21x = 180
50x = 180
x = 18/5 = 3.6
====================
13x = 46.8 degrees
16x = 57.6 degrees
21x = 75.6 degrees
