Question 664811: In triangleABC, rayAB is congruent to rayBC. If m< A=37 degrees, find m

If AB congruent to BC, then angle C (the angle opposite AB) has to be congruent to angle A (the angle opposite BC). So both A and C measure 37 degrees. So B has to measure 180 - (37 + 37) since the sum of the angles of any triangle is 180 degrees.
