Working with the graphs of trigonometric functions Working with trigonometric relationships in degrees Using the sine and cosine rules to find a side or angle in a triangle Using bearings in ...

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

to calculate unknown values based on known values. For example, if you know the length of one side and the angle opposite to it in a right triangle, you can use trigonometry to find the length of ...
