Answer:
10
Step-by-step explanation:
1. Write an equation to represent the ratio of the sides to the corresponding sides in the second figure.
6/9 = x/15
6 and x are both numerators because they are corresponding sides and 9 and 15 are both numerators because they are corresponding sides.
2. Solve for x.
multiply both sides by 9
6 = 9x/15
multiply both sides by 15
90 = 9x
solve for x by dividing both sides by 9
x = 10
