Right-triangle trigonometry and solving triangles

By the end you’ll be able to

• Use the sine, cosine and tangent ratios to find missing sides and angles in right triangles
• Use complementary-angle relationships (the sine of an angle equals the cosine of its complement)
• Apply the Law of Sines and the Law of Cosines, when given, to solve non-right triangles
• Solve angle-of-elevation, angle-of-depression and other applied trigonometry problems
