✪ Question ✪

If an exterior angle of a triangle is 130' and one of the interior opposite angle is 60, find the other interior opposite angle. And draw the figure.

✪ Given ✪

Exterior angle = 130°

One interior opposite angle = 60°

✪ To find ✪

The other interior opposite angle.

✪ Solution ✪

Let the other interior opposite angle be x°.

As the sum of the opposite interior angles is equal to the exterior angle, we can say-

x + 60 = 130

⇒x = 130 - 60

⇒x = 70

✪ Hence ✪

x = 70

Other interior opposite angle = x° = 70°

✪ Therefore ✪

The other interior opposite angle is 70°.

Please refer to the attachment for the figure.
