Step-by-step explanation:

By fig we see AB || EC

==> When Line EC is extended to X (we take it)

angle ABC = angle BCX. (alternate interior)

So angle BCX = 87°

Since, angle BCX + angle BCA + angle ACE =180° (linear pair)

So,angle BCA = 180°-(87+75)°

=18°

Also , angle BCA + angle ACD =180° (linear pair)

so angle ACD =180°-18°

==> angle ACD =162°. (ANSWER)
