To find the angle when you know its sine value, you use the inverse sine function, often written as $\arcsin$ or $\sin^{-1}$ on a calculator.

We had the equation $\sin(2\theta) = \frac{5}{6}$ .
To find the value of $2\theta$ , we apply the inverse sine function to both sides:
$2\theta = \arcsin\left(\frac{5}{6}\right)$
Using a calculator, input $\arcsin(5 \div 6)$ .
$\arcsin\left(\frac{5}{6}\right) \approx 56.44269^\circ$
So, $2\theta \approx 56.44^\circ$ .
To find $\theta$ , we divide this value by 2
$\theta = \frac{56.44^\circ}{2}$ $\theta \approx 28.22^\circ$
This is how the angle of projection was calculated.
