Study Notes
Tangent Ratio Basics
- The tangent ratio compares the length of the side opposite an acute angle to the length of the side adjacent to the angle.
- It is a fundamental concept applicable to right triangles.
Tangent Characteristics
- The tangent of an angle is defined as the ratio of the opposite side to the adjacent side.
- The tangent ratio can vary, being greater than one depending on the angle.
Right Triangles
- Tangent ratios are exclusively used in the context of right triangles, where at least one angle is acute.
Angle Measures and Calculations
- For an acute angle of 22° in a right triangle, the legs can be represented by lengths of 2 and 5.
- If sin A = 3/5 and cos A = 4/5, then tan A equals 3/4.
- The tangent of a 45° angle is equal to 1, making it unique among angles.
Angle Measurement Problems
- For specific angles based on given tangents, examples include finding angle A as 32° and another A measure as 63°.
- If the tangent of angle A equals 2.1445, angle B is found to be 25°.
Solving for Unknowns
- When given equations, such as tan20 = X/10, one can derive x to be approximately 18.7.
- Equivalents for tan 40° include expressions like COS 50/SIN 50 and SIN 40/COS 40.
Special Cases
- The tangent ratio can lead to various results in angle measurement scenarios and calculations, reflecting the relationship between angles and sides in right triangles.
