Solution

The correct option is A
R = 3 + 12 = 15 m
$N o w, y = x t a n θ [1 - \frac{x}{R}] 5 = 3 t a n θ [1 - \frac{3}{15}] \Rightarrow θ = t a n^{1} [\frac{25}{12}]$

The correct option is A R = 3 + 12 = 15 m Now, y=xtan θ[1−xR]5=3 tan θ[1−315]⇒θ=tan1[2512]

The correct option is A
R = 3 + 12 = 15 m
$N o w, y = x t a n θ [1 - \frac{x}{R}] 5 = 3 t a n θ [1 - \frac{3}{15}] \Rightarrow θ = t a n^{1} [\frac{25}{12}]$
