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

**Ans: **Here, let’s start values of sin & cosine for θ = 30^{0} and 45^{0}

We know that sin 30^{0 }= , cos 30^{0} = , cos 45^{0} =

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.**
