Question

What is the measure of an exterior angle if its adjacent interior angle measures 65^∘?

पर्याय

• 65^∘

• 130^∘

• 90^∘

• 115^∘

Answer 1

115^∘

Explanation:

An exterior angle of a triangle is adjacent and supplementary to its corresponding interior angle.

Therefore, their sum is 180°.

Thus, 180^∘ − 65^∘ = 115^∘.
