Answer:
Step-by-step explanation:
<u>Given :- </u>
And we need to find out its value . Firstly we know that 330° lies in 4th quadrant . And In fourth quadrant , cosine and secant are positive . Therefore , the result will be positive. Now we know that ,
<u>Using this , </u>
And the value of sec 30° is ,
And by question we need to write it with a rational denominator .So on rationalising the denominator , we have ,
<u>Hence the required answer is 2√3/3.</u>
