△UVW~△JHI. Find UV.

UV = __

UV = 5 units

Step-by-step explanation:

ΔJHI is just a scaled-up version of ΔUVW

So, the scale factor here is = 9

Therefore, because UV is the scaled-up version of JH,

We get,

JH/9

=> 45 / 9

=> 5

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

answer: .64
