Answer 1

Answer:

x = 32°

y = 64°

Step-by-step explanation:

From the figure, we can note the following:

2x = y (Alternate interior angles) ———————— 1

y + 3x + 20° = 180° (Adjacent linear pair)

y = 180° - 20° - 3x = 160° - 3x —————————— 2

From equations 1 and 2, we have

2x = 160° - 3x

5x = 160°

x = 160/5 = 32°

Substituting this value of x in equation 1, we get

2 (32°) = y

y = 64°
