Answer:

b. 38

Step-by-step explanation:

Parallelogram ABCD, AB ║ CD

so <1 = 38 (alternate interior angles are equal)

Answer:

38°

Step-by-step explanation:

This is can be found by congruence theories.

If you look carefully, ∠BCA is = to ∠CAD through alternate interior angles.

So ∠1 is measured 38°.

For better explanation, CA is the transversal line through the parallel BC and AD. That is how alternate interior angles are used.
