Question

Find the values of 2 root 2 Cos45°.cos60° + 2 root 3 Sin60°. tan60° -cos0º​

Answer 1

Step-by-step explanation:

$2 \sqrt{2} \times \cos(45) \times \cos(60) + 2 \sqrt{3} \sin(60) \times \tan(60) - \cos(0)$

$= 2 \sqrt{2} \times( 1 \div \sqrt{2} ) \times (1 \div 2) + 2 \sqrt{3}( \sqrt{3 } \div 2) \times \sqrt{3} - 1$

$= 1 + 3 \sqrt{3} - 1$

$= 3 \sqrt{3}$
