If in a

\triangle A B C

\cos A \cos B+\sin A \sin B \sin C=1

, then

a: b: c

is equal to

View answer and explanation

Correct option: A

1: 1: \sqrt{2}

Option A (

1: 1: \sqrt{2}

) is correct because the given condition implies that the triangle is a right-angled isosceles triangle, leading to the ratio of sides
