Answer:
48, 54 and 60
Step-by-step explanation:
Let the three multiples be 6x, 6(x+1) and 6(x+2) respectively.
6x+6(x+1)+6(x+2)=162
6x+6x+6+6x+12=162
18x=144
x=8
Therefore, the three multiples are 6(8), 6(8+1) and 6(8+2)
i.e. 48, 54 and 60
y=-1
perhaps replace x with 1
They must equal 180°. Supplementary angles equal 180°
