Question

Solve for x! show work please < 3

Answer 1

x = 10

Explanation:

since the two shapes are similar , setting them up in proportion can help to find x, like this ;

2x - 10 / 15 = 6 / 9......cross multiply

9 × ( 2x - 10 ) = 6 × 15

18x - 90 = 90

18x = 90 + 90

18x = 180

x = 10

Answer 2

x=10

Explanation:

First off those are not triangles, tell someone that if you can and it hasn't been said already. Since 6 and 9 correspond we know the big triangle is 1.5 times the size of the small one. Because of this, we can set 1.5(2x-10) or 3x -15 = 15. x = 10. You can also just take 15/1.5 to get 10 but the stuff above is the work.
