Find the m∠BCA, if m∠DCE = 70° and m∠EDC = 50°.50°60°70°80°

Q:
Find the m∠BCA, if m∠DCE = 70° and m∠EDC = 50°.50°60°70°80°
Accepted Solution
A:
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
