Solve the following problems. given: ab ≅ bc and ae = 10 in, m∠fec = 90° m∠abc = 130°30' find: m∠ebc, ac

Because BA ≅ BC, we know the triangle is isosceles. Because ∠FEC=90°, we know BE is a median and angle bisector of ∠ABC.

Hence ...

... AC = 2×AE = 20 in

... ∠EBC = (1/2)×∠ABC = 65°15'

y/x of point b= y/x of point a
