Question

What is the value of m in the figure below? In this diagram, ΔABD ~ ΔBCD.

Answer 1

√126

Option D is the right option.

solution,

`(ac)/(bc) = (bc)/(dc) \\ or \: (18)/( m) = (m)/(7) \\ or \: m * \: m = 18 * 7(cross \: multiplication) \\ or \: {m}^(2) = 126 \\ m = √(126)`

Hope this helps..

Good luck on your assignment.
