By increasing the sides of a triangle in a single direction, obtained

1.	By increasing the sides of a triangle in a single direction, obtained exterior angles are 110°, 115° and x°, then find the value of x.
Answer» We know sum of all exterior angles of a regular polygon = 360° ⇒ 110° + 115° + x° = 360° ⇒ 225° + x° = 360° ⇒ x° = 360° – 225° ⇒ x° = 135°

By increasing the sides of a triangle in a single direction, obtained exterior angles are 110°, 115° and x°, then find the value of x.

Answer»

We know sum of all exterior angles of a regular polygon = 360°

⇒ 110° + 115° + x° = 360°

⇒ 225° + x° = 360°

⇒ x° = 360° – 225°

⇒ x° = 135°
