Step-by-step explanation:

Answer:
Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63
Step-by-step explanation:
78/2 = 39
(Angle 2/2 = Angle 1)
78 - 15 = 63
(Angle 2 - 15 = Angle 3)
39 + 78 + 63 = 180
(Angle 1 + Angle 2 + Angle 3 = 180)
The maximum number of shirts I can buy is 2.
14.50 x 2 = 29
14.50 x 3 = 43.5
Two shirts cost 29 dollars, and 3 shirts cost 43.5 dollars. Since $43.5 is higher than the money I currently have, I can only buy 2 shirts.
