Answer 1

Answer:

x = 70°

y = 60°

Step-by-step explanation:

Using exterior angle property of the triangle.

50° + x = 120°

⇒ x = 70°

Now, we can find y by using the sum of angle property or using the linear pair property.

120° + y = 180° ⇒ y = 60°

or, 50° + 70° + y = 180° ⇒ y = 60°

terms used,

Exterior angle property: An exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.

Linear pair: A linear pair is a pair of adjacent angles formed when two lines intersect. And the sum of these two angles is 180°

Sum of angle property of triangle: Sum of all angles of a triangle is 180°
