Answer:

? = 45

Step-by-step explanation:

Since the triangles are similar, we can use proportions

20       20+8

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

?           ? + 18

20         28

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

?           ? + 18

Using cross products

20 ( ? +18) =  = ? * 28

Distribute

20 ? + 360 = 28 ?

Subtract 20 ? from each side

360 = 8?

Divide each side by 8

360/8 = ?

45 = ?
