# Evaluate the following:(i) (ii) (iii) (iv) (v)

Given is the table of Trigonometrical ratios for different values. Use the values from table for solving the questions.

(i) sin60° cos30° + sin30° cos 60°

= 1

(ii) 2 tan245° + cos230° - sin260°

= 2 (1)2 + (√3/2)2 - (√3/2)2

= 2 + 3/4 - 3/4

= 2

(iii)

As the denominator has an irrational number, we need to rationalize the fraction

(iv)

(v)
