If an exterior angle of a triangle is 130° and one of the interior opposite angle is 60°. Find the other interior opposite angle.

Answer»

Let the other interi6r opposite angle be = x°

Give interior opposite angle be = 60°

Now sum of the interior opposite angle = exterior angle

x° + 60° = 130°

x° = 130° – 60° = 70°

∴ The other interior opposite angle = 70°
