Supplementary means adds to 180
A+B=180
B=73
A+73=180
minus 73 both sides
A+73-73=180-73
A+0=107
A=107
A=107 degrees
The compounding equation is

To see how they are related, let us solve the two equations.
FIRST EQUATION



SECOND EQUATION



Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
10. This is because 3 evenly goes into 30 without a remaining fraction
