Question

In triangle ABC, A-M-B and A-N-C and MN||BC. If AM/MB=2/3 and AC=25, find NC.
​

Answer 1

Answer:

NC=15

Step-by-step explanation:

As AM/MB=AN/NC

THEREFORE,2/3=AN/AC-AN.

( BECAUSE WE CAN ALSO WRITE NC=AC-AN.)

THEREFORE, 50-2AN=3AN

SO AN=10.

NOW AS WE KNOW THAT, NC=AC-AN

NC=25-10=15.
