The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...
The aim is to find the value of Ɵ that makes cosƟ equal 16/32 ... that contains both \(o\) and \(h\) is the sine (sin) ratio. Practise finding angles in right-angled triangles with this quiz.
