What is trigonometric indentity?
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
Given that the hypotenuse of the triangle is 42 and the angle B is 17 degrees.
The side AC will be calculated as below:-
sin(47) = P / 42
AC = 42 x sin42
AC = 12.27
Therefore, the length of the side AC will be 12.28 units. The correct option is C.
