Answer:

3 = ?

Explanation:

The triangles are similar, so we can use ratios

15 12 -2

------ = --------------

15+? 12

15 10

------ = --------------

15+? 12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

3 = ?
