When a figure is dilated, this means the corresponding sides of the shape is enlarged in a uniform multiple. In thsi case, the ratio of the sides remains the same. Thus, when ratio of the sides remains the same, the corresponding angles are also congruent in the dilated figure.
H=-6 is the answer after substituting
72:3=24
24-1=23
24+1=25
23+24+25=72
23 is the smallest
