Question

Find the missing side length of m.

Answer 1

m=4

Explanation:

Since we know that quadrilateral ABCD is similar to QRST, we know that the side lengths will be proportional to one another. As such, we should take a ratio to determine the side length of m.

`(ST)/(CD)=(RS)/(BC)\\\\(6)/(15) =(m)/(10)\\`

`(6*10)/(15) =m\\m=60/15=4`

m=4
