Question

Which pair of the angles of projection of projectile have same range.

(a) 30°, 70°
(b) 1
°, 89°
(c) 15°, 85°
(d) 30°, 40°​

Answer 1

Answer:

B) 1, 89

Explanation:

When the angles are complementary, i.e their sum is equal to 90°

For example if one angle is 60° then the angle at which the range is gonna be same is 30°.

How?

Coz 60 + X =90, which gives X out to be 30
