Given L || M find the value of unknown angles in each of the following figures​

Answer 1

x = 120°

y = 60°

Explanation:

✔️since, lines l and m, area parallel, therefore,

x = 120° (they are corresponding angles having matching corners. Thus, corresponding angles are congruent to each other)

✔️x + y = 180° (linear pair angles)

Plug in the value of x

120 + y = 180

Subtract 120 from each side of the equation

y = 180 - 120

y = 60°
