Question

Given ∆ABC, sin A= , cos A = , tan A = 

 

The image shows a right-angled triangle labeled as triangle ABC. The right angle is at vertex C. The side opposite the right angle, the hypotenuse, is labeled as \( c \). The side adjacent to angle A is labeled as \( b \), and the side adjacent to angle B is labeled as \( a \). The vertices of the triangle are labeled as follows: the bottom left corner as \( A \), the top corner as \( B \), and the bottom right corner as \( C \). This diagram represents the fundamental elements of a right triangle, often used in trigonometry and geometry to explain the Pythagorean theorem: \( a^2 + b^2 = c^2 \).
