Question

In triangle abc ab=ac=13 and bc=10 calculate the length of perpendicular from a to bc

Answer 1

Answer:

here is the answer

Step-by-step explanation:

when we construct a perpendicular bisector from a to bc let it be ad, ad=dc=5

in  Δabd

ab² =ad² +bd²

13 ²= ad² + 5²

169- 25= ad²

ad=√144

ad =12
