the two triangle are similar , then the angles of the smaller triangle is the same with the bigger triangle, so "d" is already not an option now to get the value of y try this proportion 5:30 = x:18

5 x 6 =30 X x 6 =18? X=3 angle y would be equivalent to the angle in the second triangle. Kay? >o<

Yes, A is correct In similar triangle, corresponding angle are congruent, so y = 53 Also, in similar triangle, the lengths of corresponding sides are proportional. You know the ratio 30/5. The other sides must be in the same ratio, so 18/x = 30/5

yeah~ because if they really are proportional, the sides would have to be multiplied by the same constant.
