Answer 2

Answer:

x = 130°

y = 30°

z = 130°

w = 150°

Step-by-step explanation:

In triangle ABC,

Sum of three angles of a triangle = 180°

A + B + z = 180°

20 + 30 + z = 180

z = 180 - 50

z = 130°

DE || BC, AB and AC are transversals.

Then, y = 30° (corresponding angles)

x = 130° (corresponding angles)

Angles on a straight line = 180°

w + y = 180°

w + 30 = 180

w = 180 - 30

w = 150°
