help!?!? What is BCA? for the triangle shown!

OpenStudy (anonymous):

all the interior angles of a triangle have to add to 180 degrees, so if you already know that one is 130 degrees, and the other two are the same measurement, then 180 - 130 = 50 and 50 divided by 2 is 25 so: BCA is 25 degrees! hope i helped:D
