**Trig 3D problems Iona Maths**

By alternate interior angles it is equal to the top part of the angle indicated by the red arc, which is above the horizontal. And we can calculate the bottom part of that angle by subtracting 270°-230°=40°. So the angle indicated by the red arc is 35°+40° or 75°. Now we can use the law of cosines to find the length of the green line D.... In this lesson we have returned to the topic of right triangle trigonometry, to solve real world problems that involve right triangles. To find lengths or distances, we have used angles of elevation, angles of depression, angles resulting from bearings in navigation, and other real situations that give rise to right triangles. In later chapters, you will extend the work of this chapter: you
