find the length of side b

[facto2]

My instructor said I needed to relook at how I calculated side b. I dont understand because i did the exact same thing for side c and it was graded as correct. Am I missing something?Thank you for your time.

what law did you use? id use the law of sines. and then after getting both b just do pythagoreans theorms to get c! also finding the other angle is easy just add the two given and subtract them from 180!

You used a / sinA = 14.4 / 72.6 ; A is 52.6, not 72.6

NO. Pythagorean Theorem applies ONLY to right triangles.
