Use the following figure to find the value of x

Advertisements

Solution

The sum of exterior angles of a quadrilateral

⇒ y + 80° + 60° + 90° = 360°

⇒ y + 230° = 360°

⇒ y = 360° – 230° = 130°

At vertex A,

∠y + ∠x = 180° (Linear pair)

x = 180° – 130°

⇒ x = 50°

  Is there an error in this question or solution?
