Answer:
Explanation:
Since they are similar they have the same angles and their sides are proportional to each other. You can solve it by using ratio. we are given the side length of line PQ and KJ we can find the ratio which is 1:8. If we apply this ratio to the line PR and LJ we can find the x value: 1:9 = 3+x:54.
Therefore the x value is 3.
