Question

an exterior angle of a triangle is 80 and the one interior opposite angle is 30 the other is
​

Answer 1

Answer:

50

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the interior opposite angles. This theorem is called Exterior Angle Theorem.

Here exterior angle = 80

Interior angle = 30

Therefore other interior angle = 80 - 30 = 50

Answer 2

50°

Step-by-step explanation:

Q.

An exterior angle of a triangle is 80° and the one interior opposite angle is 30°, the other is

Solution -

Let the other angle as x

Remember -

Exterior angle = Sum of two opposite interior angles

=> 80° = 30° + x

=> 80° - 30° = x

=> 50° = x

=> x = 50°

So, the other interior angle = 50°
