Question

8. Show that for complementary angles, the range are equal​

Answer 1

Explanation:

if one angle is x. another ange is 90-x .

range = u²sin(2∅) / g

range one = u²sin2x/g

range two = u²sin( 180-2x ) / g = u²sin2x / g

range one and range two are equal . x and 90-x are complementary angles .

hence proved
