Tree Height sent us to triangles!!! Pulled out the protractor n worked the angles. Then we got a foretaste of sin cos tag!!!! Girls took the trip but I enjoyed it!!! S2 Triangle showing Opposite, Adjacent and Hypotenuse

\displaystyle{ \begin{array}{ccc} \sin A &=& \displaystyle\frac{\text{opposite side}}{\text{hypotenuse}}\\ \\ \cos A &=& \displaystyle\frac{\text{adjacent side}}{\text{hypotenuse}}\\ \\ \tan A &=& \displaystyle\frac{\text{opposite side}}{\text{adjacent side}} \end{array} }
