Thank you

[@RaghavMukhija]

In isosceles triangle BCD, ∠ D = ∠ B = θ Therefore, θ cannot be obtuse in this scenario as it violates the angle sum property of triangle(sum of angles of a triangle = 180°).

[@Cheenta]

Rightly pointed out Raghav

[@rishabhtiwari2325]

8:56 because there cant be more than one obtuse angle in any triangle

[@Cheenta]

Right!

Find sides by cos rule,then Directly use ptolemy theorem,in AMC you dont have much time,don't waste time watching these

Approach maters , not a way to do a single problem. He is PhD in maths , a lot more experienced than you. You should respect each idea .♥️

Dear student, Please note that at the very beginning of the video (and in the thumbnail) we mentioned that we will explore Trig Bashing. The main goal was to take a tour of that strategy and not the most efficient solution of this problem.
