Question

Plz Help and explain the process!....

Answer 1

m = 3

Explanation:

Since model ABCD has all equivalent side lengths, QRST is the same way, just smaller.

(Not sure if this is right, just the way I learned it!)

Answer 2

I think m = 3. Because on the other all sides are equal. (12) and the other side is 3 so that most likely means all sides are 3. Hope this helps
