Question

This is geometry

Find the missing length indicated

Note: Not drawn to scale

Answer 1

? = 9

Explanation:

First, deduce the length top part of the left side.

8 - 6 = 2

So, we can now label that top part 2.

Finally, compare the ratios of the sides.

2 : 6 = 3 : ?

2 * (3/2) : 6 * (3/2) = 3 : ?

? = 6 * (3/2)

? = 9
