Question

Please help me with this question.

Answer 1

38°

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.

Answer 2

b. 38

Explanation:

Parallelogram ABCD, AB ║ CD

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