Application +4 | -1

The sides of a triangle are

\sin \alpha \cos \alpha

and

\sqrt {1 + \sin \alpha \cos \alpha }

for some

0 < \alpha < \frac{\pi }{2}

. Then, the greatest angle of the triangle is

View answer and explanation

Correct option: C

120^\circ

Option C (120°) is correct because, with the given side lengths, the cosine of the greatest angle simplifies to -1/2, implying the angle is 120°.
