Mathematicians had long thought that using trigonometry to prove the theorem was unworkable, given that the fundamental ...

The adjacent side (\(a\)) is next to the angle in question (\(x\)). The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles. An equilateral ...

Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...
