Question

Find the value of 2√2 cos 45°cos60° + 2√3 sin 30° tan60° - cos 0°​

Answer 1

Answer:

3 √3

Step-by-step explanation:

2 √2 cos45°. cos60° + 2 √3. sin60°. tan60° - cos0 °

= 2 √2 . 1/ √2 . 1/2 + 2 √3 .  √3/2 .  √3 - 1      

hence,

cos45°=1/ √2 ,

cos60°=1/2 ,

sin60°=  √3/2 ,

tan60°=√3 and

cos0°=1            

= 1 + 3 √3 - 1

= 3 √3

Just u need to substitute the values
