Thus far our study of trigonometry has been limited to right triangles. Application of trigonometry to oblique triangles is studied in this chapter. Oblique triangles are often encountered in shop ...

Draw the right-angled triangle OVC and label the sides. The angle between VC and the plane is (\(y\)) It is not possible to use trigonometry to calculate the angle because the length of another ...

What began as a bonus question in a high school math contest has resulted in ... the relationship between the three sides of ...

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 ...
