Question

In the given figure angel D and angel F are respectively, if angel B = 30°
angel C =20°, LE = 130°​

Answer 1

$\huge\underbrace\pink{ANSWER:-}$

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°
