Where are they getting that equation from?
4 - alpha / 6 - alpha = 10/8
the slope of AB isn't given
Slope of BC is found out
By using reflection of A in angle bisector and C
And then B must be of the form (α, α) because it lies on y=x
without knowing the line equation of BC, how would i know that (6,4) lies on it
It's a theorem. The reflection of any vertex of a triangle through either of the angle bisectors not passing through it lies on the side of the triangle opposite to it.
oh what
that sounds like some niche theorem they found and decided it would be nice for 2 questions
Its been asked several times before.
my initial thought was that since 2AB = BC i'd equate the distances to find alpha, but that turned into a huge mess
well ok
ill look it up
thanks
