The trigonometric function gives the ratio of different sides of a right-angle triangle. The angles that make the trigonometric statements true are Sin A= Cos B and Sin B = Cos A.
What are Trigonometric functions?
The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
The angles that make the trigonometric statements true are,
Sin A= Cos B = BC/AB = 12/13
Sin B = Cos A = AC/AB = 5/13
