$$\theta=\arccos0.92341853$$ Similarly, $$\theta=\cos^{-1}0.92341853$$ Now we use the calculator to calculate for $\theta$. However, as the question asks for the value in decimal degrees, do not forget to switch the calculator to the DEG environment. Using calculator, I get $$\theta\approx22.6^\circ$$
