Ad¯¯¯¯¯ , bd¯¯¯¯¯ , and cd¯¯¯¯¯ are angle bisectors of the sides of △abc . cf=8 m and cd=17 m. what is de ? enter your answer in the box.

DE= 15 m

Explanation:

Since, in ,

After applying, Pythagoras theorem,

Thus, m

Again, in and ,

( Right angles)

BD=BD ( common edges)

(BD makes the angle bisector of angle B.)

Thus, according to AAS condition-

So, DE=DF (CPCT)

Therefore, DE=DF=15m⇒DE=15 m

(x+3)(x+7)
