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 ...
The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...
