Step-by-step explanation:
Answer: 13
Step-by-step explanation:
180 - (154 + 13) = 13
the triangle is isosceles
Because of the parallel lines, angles A and DCE are congruent.
Also, angles E and BCA are congruent.
That makes angles B and D congruent.
m<DCE = 70 and m<EDC = 50, so m<E = 60
m<BCA = m<E = 60
