Answer:
BC=25
Step-by-step explanation:
The provided data in the figure is different from the written text. We'll use the set of conditions in the figure
We know the triangle is isosceles, so the sides AC and AB are equal, i.e.
4x+4=6x-14
Operating
4+14=6x-4x
x=18/2=9
Knowing that x=9, then
BC=2x+7=18+7=25
Note: If we used the data provided in the text, the answers would be
x=11, BC=25
