we are given
Firstly , we can distribute tan^2 inside
we get
now, we can simplify it
we know that
tan=1/cot
so, tan^2 will get cancelled with cot^2
so, option-C..............Answer

Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;
The vertical component of the velocity is calculated as;
Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)
