Hence, the value of:
Step-by-step explanation:
We are given a trignometric formula for the given angle 'x' as:
So, we consider a right triangle such that it's perpendicular side is 5 units and the hypotenuse is 13 units.
Hence, we get the third side of the triangle i.e. CB using the Pythagorean Theorem as:
Hence,
Now, we know that:
