Any similar right triangle created using AA Similarity will have proportional sides so the trig ratios will be the same. The values of trig ratios depends on the measure of the angles. Scientific and graphing calculators can give the trig ratios for any angle. Example 2 (p 366): Use a Calculator to Evaluate Expressions

We simply take the inverse sine of both sides. On the left hand side, the sine and inverse sine undo each other and we are left with θ by itself. In order to plug this into your calculator, you need to use the 2nd function of the sine function. You should get an answer of 41.8°. Cosine and tangent have similar inverse functions, cos-1 and tan-1.

Define the tangent, sine, and cosine ratios for both the acute angles in a right triangle. State and apply the relationship that exists between the trig functions of an acute angle of a right triangle and those of its complement. Recognize the secant, cosecant and cotangent functions as the inverse functions of sine, cosine and tangent. Materials
