Solve for the missing sides and angles

Angle B measures 83.75 degrees
Side c has a length of 173 units
Side b has a length of 172 units

Coordinates are always labeled in this general layout:

Angle A measures 7.3 degrees
Side a has a length of 22 units
Angle C measures 88.95 degrees

A is at coordinates (21, 275)
B is at coordinates (0, 103)
C is at coordinates (22, 103
