Question

Plz answer it its urgent ​

Answer 1

Solution :

As we know that, the exterior angle is equal to the sum of two opposite interior angles of a triangle.

☆ Therefore,

↣ x = 40° + 60°

↣ x = 100°

∴ The value of the unknown exterior angle x is 100°.

Answer 2

Step-by-step explanation:

two angles given = 60° and 80° let, third angle y

y + 60° + 40° = 180° (sum of interior angle of a triangle 180°)

y = 180° - 100°

y = 80°

y + x = 180°( linear pair )

x = 180°- 80°

x = 100°
