In this case side A is the opposite side and side B is the adjacent side. Trigonometry Basics : how to find missing sides and angles. We have. What happened to the others? We know that the tangent is calculated as the ratio of the opposite side to the adjacent side. Angle B A C is the angle of reference. Consider Figure 5, where a right triangle is given with the measure of one acute angle and one side. ", if in trigonometry the ratios of the sides of a triangle are called 'trigonometric ratios' then what if the triangle is not a right triangle. The trigonometric identities of right triangles give us. Thus, rounded, your answer isfeet andinches. Its like a teacher waved a magic wand and did the work for me. Careful!
