Step-by-step explanation:

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
1 is 39. J don’t know about 2 and 3 though:(
11.43 hope you have a good day
a: draw a rectangle an label one side 80 and the other 115

An Infinite Number of solutions is the answer! LMK if you have any more questions, and have a nice day/evening.
