Answer: 111.1
Step-by-step explanation: 333.3/3 = 111.1
Let x be the angle, the complement is 90-x. the sup is 180-x.
So 180-x = 3(90-x)+12
180-x=282-3x
180+2x=282
x=102
x=51
2x = x/2 - 6.....multiply both sides by 2
4x = x - 12
4x - x = -12
3x = -12
x = -12/3
x = -4
3x = 12......3(-4) = 12.....-12 = 12...false......so 3x = 12 is not true because x = -4
