Will Humbled Trader sessions be profitable? @Alexis Olson I think that a majority of people, when they have the choice, will opt for $\tan^{-1}=atan$ instead of $\cos^{-1}$, giving: $\tan\theta=\frac{HD}{BD}=\frac{5}{\sqrt{53}}\approx 0.6868\implies \theta=atan(0.6868)=0.6018 rad = 34.48^\circ.$, The reason of this preference is that $atan$ has a "smoother behavior" than $acos=cos^{-1}.$. I get $2 \cdot \sqrt{53} \cdot \sqrt{78}\approx 128.59$ in the denominator. The angle is the amount of turn between each arm. All corners of a cuboid are right angles and opposite faces or sides are equal. Add a comment | 1 $\begingroup$ I think you have difficulty seeing B is perpendicular to R, which in fact it is also perpendicular to any line through intersection of H-V. $ \tan \sigma= \frac{B}{R} $ So, I marked out all right angles on your sketch.
