Question

In the given figure, AD is the median ,then find ∠BCA .

please answer i will make u as brainiest ​

Answer 1

Answer:

ABC is an isosceles triangle since AB=AC. ∠B=∠C=35

∘

∠A=110

∘

(∵∠A+∠B+∠C=180

∘

)

In an isosceles triangle, median (AD) to the base BC is the angular bisector of ∠A

Hence, ∠BAD=55

∘

Answer 2

Answer:

In the given figure,

AD is the median

∠ABC = 35 ⁰

And AB is equal to AC

Therefore ∠ABC = ∠ACB

Hence ∠ACB = 35 ⁰ (Angles opposite to equal sides are equal)

Hence proved
