To solve these kind of problems, users can treat the measures like variables.TOA - Tangent is equal to Opposite over Adjacent.CAH - Cosine is equal to Adjacent over Hypotenuse.SOH - Sine is equal to Opposite over Hypotenuse.users can remember the formulas using Sal's ' Soh Cah Toa' method in which:.Use trigonometric measures to solve for missing information of side lengths - This problem has users to look at the trigonometric measures of any angle in a triangle given one side length and solve for any other side length in the triangle.There is one type of problem that shows up in this exercise:

This exercise is similar to the exercise, Trignometry 1.5, just that some of the sides are square root values. The Trigonometry 2 exercise appears under the High school geometry Math Mission, Trigonometry Math Mission and Precalculus Math Mission. The objective of this exercise is to help users find the length of sides of triangles knowing all three trigonometric measures of any angle in the triangle.
