Question
Given ∆JKL, sin K= , cos K = , tan K = \

Transcribed Image Text:This image depicts a right triangle labeled △KLJ. In this triangle:
- \( K \) is the vertex opposite the right angle.
- \( L \) and \( J \) are the vertices at the base, with \( LJ \) being the base of the triangle.
- The side \( KL \) is labeled as \( j \).
- The side \( LJ \) is labeled as \( k \).
- The hypotenuse \( KJ \) is labeled as \( l \).
The triangle includes a right angle symbol at vertex \( L \), indicating that \( \angle KLJ \) is a right angle. This configuration is typically used to demonstrate concepts in trigonometry and geometry, such as the Pythagorean theorem or trigonometric ratios.
