Web3 de ago. de 2014 · Now, in general, if we know two side lengths of a triangle (call them x and y) and the angle measure between them (call it θ ), then the area of the triangle is given by A = 1 2 x y sin ( θ). Applying this to our scenario, since the angle between the two given sides can vary, then so too can the area of the triangle.

The top angle is the apex angle of the prism, 𝐴. We also know that the interior angles on the left and right are both 9 0 ∘, since these angles are formed by the faces of the prism and the normal lines to these surfaces. This leaves us with one unknown angle: the interior angle at the bottom …
