Is this problem solvable,if it is how do i solve it-
ABC is a isosceles triagle where AB=AC .The bisector of angle C intersects with AB at the point D,if AD+CD=BC,then angle A=?
I dont know..
I see you have graph paper.
You must be plotting something
Looks like it is 100 degrees.
In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
What do i do to get angle A=100 ?
