Answer:

x = 9

Explanation:

The diagram indicates the smaller triangle is similar to larger triangle since the 2 bottom sides are parallel

Then 12/(12 + 15) = (x + 7)/(x + 7 + 20)

12(x + 27) = 27(x + 7)

12x + 324 = 27x + 189

27x - 12x = 324 - 189

15x = 135

x = 9

Answer:

x=10

15 to 12 is -3 so (x + 7) + 3 must equal 20 which is 17.
