Application +4 | -1

If the rate of increase of a side of a triangle inscribed in a circle of radius

\mathrm{R}

, is

\mathrm{R}

times the rate of increase of the measure of opposite angle, then the measure of the angle is ....... .

View answer and explanation

Correct option: C

\frac{\pi}{3}

Option C (

\frac{\pi}{3}

) is correct because using the sine rule and the given rate relationship, we can find the angle A.
