Answer 1

Answer:

In the given figure, l || m and t is a transversal.

If ∠5 = 70°, find the measure of each of the angles

∠1, ∠3, ∠4 and ∠8.

ANSWER:

Given: l∥mt is a transversal.∠5 = 70° ∠5 = ∠3 =70° (alternate interior angles)∠5 +∠8 = 180° (linear pair)or 70° + ∠8 = 180°∠8 = 110°∠1 = ∠3 = 70° (vertically opposite angles)∠3 +∠4 = 180° (linear pair)or ∠4 = 180−∠3 = 180 − 70 = 110°.
