Question

Find the length of AB.

Answer 1

AB=9

Explanation:

`(DC)/(BC)=(EC)/(AC)\\ (4)/(3)=(16)/(AC)\\\\ AC=12\\\\ AB=AC-BC\\ AB=12-3=9`

Answer 2

We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units
