Please help!!!

3 is to 2       as     n is to 7

 

3/2 = n/ 7

 

7 *  3/2  = n = .......

Since the triangles are similar, that means the ratio between each of the sides will be same.

 

You can find that the ratio between sides is 2:7 (by comparing AB to XY and BC to YZ).

 

Since we're tryna find N, you need to divide AC by two (to get 1.5) then multiply by 7.

 

The answer is 10.5
