Approximate height of the balloon above the ground in metres—

a $250.00$
b $433.01$
c $866.03$
d $1000.00$

ব্যাখ্যা

With a horizontal distance of $250$ m and an angle of elevation of $60^\circ$ , the height is $h = 250\tan 60^\circ = 250\sqrt{3} \approx 433.01$ m. This uses the basic right-triangle relation $\tan\theta = \frac{\text{height}}{\text{distance}}$ .
