Solve applied problems involving right triangles and trigonometric functions.
Solving Right Triangles
Now that we can find function values for any acute angle, it is possible to solve right triangles. To solve a triangle means to find the lengths of all sides and the measures of all angles.
Example1
In (shown at left), find a, b, and B, where a and b represent lengths of sides and B represents the measure of . Here we use standard lettering for naming the sides and the angles of a right triangle: Side a is opposite angle A, side b is opposite angle B, where a and b are the legs, and side c, the hypotenuse, is opposite angle C, the right angle.
Solution
In , we ...
