Question

Find the missing side length, m.

Answer 1

m=5

Explanation:

Since we know that triangle ABC is similar to QRS, 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.

Choose whole numbers to make the division easier

`(QR)/(AB) = (QS)/(AC) \\(10)/(6) = (m)/(3) \\(10*3)/(6) =m\\m=10*3/6 = 5`
