40.In an isosceles triangle ABC, if AB AC -25 and BC = 14 cm, then the measure of altitude from A on BC is​

1. Answer:

   ABC is an isosceles triangle with AB = AC. Altitudes are drawn to the sides AB and AC from vertices B and C. One altitude CF is found to be 4 cm and BC = 5 cm.

   Then in triangle BFC the angle BFC =90

   Then BF2=BC2−CF2=(5)2−(4)2=9⇒BF=3

   In triangle BEF & triange BFC are similler

   Then EC=BF=3

   Hope this helps you Army❤❤❤❤❤❤
