Supplementary angles ; Sum = 180

<P + <Q = 180

4x+1 + 9x - 3 = 180

13x - 2 = 180

13x = 182

x = 14

<Q =  9(14) - 3 = 126 - 3 = 123

Supplementary = 180

Setting the equation
4x + 1 + 9x - 3 = 180
Combine like terms
13x - 2 = 180
Add
13x = 182
Divide
x = 14

Plug the value of x into <Q
9(14)-3
126-3
123 is your answer
