Answer:
c, b, a
Step-by-step explanation:
The sum of the three angles is 180, so we have ...
(9x -7) +(7x -9) +(28 -2x) = 180
14x +12 = 180 . . . . . . simplify
14x = 168 . . . . . . . . . . subtract 12
x = 12 . . . . . . . . . . . . . divide by 14
Now, we can find the values of the angles.
A = 9·12 -7 = 101
B = 7·12 -9 = 75
C = 28 -2·12 = 4
The side lengths are in the same order as the angle measures. Shortest to longest, they are ...
c, b, a
