In the given figure, ΔABC is a right triangle.

Question

The figure shows the right-angle triangle ABC. B is the length of AC and a is the height of BC and c is the base of AB.
What is true about ΔABC?

A. sin(A) = cos(C) and cos(A) = cos(C)
B. sin(A) = sin(C) and cos(A) = cos(C)
C. sin(A) = cos(A) and sin(C) = cos(C)
D. sin(A) = cos(C) and cos(A) = sin(C)

Answer 1

C. sin(A) = cos(A) and sin(C) = cos(C)
