Answer 2

SOLUTION

TO DETERMINE

The value of cos ( 760° - x )

EVALUATION

Here the given Trigonometric ratio is

cos ( 760° - x )

Let us assume that x is an accute angle

Now

cos ( 760° - x )

= cos ( 8 × 90° + 40° - x )

The angle ( 760° - x ) lies in first quadrant

So cos ( 760° - x )

= cos ( 8 × 90° + 40° - x )

= cos ( 40° - x )
