Question

two stones are projected with the same speed but making different angle with the horizontal the ranges are equal if the angle of projection of one is pie / 30 and its maximum height is H, then the maximum height of the other is​

Answer 1

Answer:

Explanation:

in right angle triangle one angle is 90°

let another two angles are A and B

now,

A +B +90° =180°

A + B =90°

given,

A -B =2π/5 =2(180°)/5 =72°

solve both equation ,

A + B= 90°

A - B =72°

A =162/2 =81°

and B =9 °

hence, smallest angle is 9°
