Q)  Evaluate: 2√2 cos 45° sin 30° + 2√3 cos 30°

Ans:  Here, let’s start values of sin & cosine for θ = 30⁰ and 45⁰

We know that sin 30⁰ = , cos 30⁰ = , cos 45⁰ =

We submit these values in the given question, we get:

2√2 cos 45° sin 30° + 2√3 cos 30°

= 2√2 + 2√3

=

= 1 + 3 = 4

Therefore, the value of 2√2 cos 45° sin 30° + 2√3 cos 30° = 4.
