(90-x) + (180-x) = 162

solve for x

Call the angle A, its complement C, its supplement S.

A + C = 90

A + S = 180

C + S = 162.

Three equation and three unkmnowns.

I would solve equation 3 for C and substitute that into equation 1. Then solve 1 and 2 simultaneously. Post your work if you get stuck.
