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 ...
We can use trigonometric identities to calculate angles as well as the lengths of sides. In order to calculate angles we must know two sides of the right-angled triangle. Look at this triangle: We ...
Trigonometry is a branch of mathematics that studies the relationships between the angles and sides of triangles. It is useful for solving problems involving distances, heights, angles, and rotations.
