Question

a peacock is sitting on the top of a tree. itobserves a serpent on the ground making an angle of 30°. the peacock catches the serpent in 12 s with the speed of 300m/min.bwhat is the height of the tree

Answer 1

here, drawing the triangle, the angle on base is 60 degree (it's a right angle triangle),
also the hypotenuse is speed*time
i.e. hypotenuse=60m
sin(theta) is opposite/hypotenuse,
sin(60)is √3/2,
here, sin 60 is x/60,
here, x is 30√3
that's the height of tree, which is 30√3 m
