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

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
