Answer 2

Answer

∠y = 60°

∠y = 60°∠x = 120° 

Explanation

We know that Angle Sum of a Triangle = 180°

∠y = 180° -(50° + 70°) [ASP of Triangle]

∠y = 180° - 120

∠y = 60°

∠x = 180° - (∠y) [Linear Pair]

∠x = 180° - 60°

∠x = 120°

More Information

Angle sum of a quadrilateral = 360°

Angle sum of a quadrilateral = 360°

Angle sum of a quadrilateral = 360°

Tip

To find the angle sum of any polygon we can use the formula (n - 2) × 180,where n is the number of sides of a polygon.
