Question

Find the value of: 2 cos 30⁰ + 4 sin 60⁰ + 5 tan 60⁰

Answer 1

Answer:

Step-by-step explanation:

Given,

cos 30° = √3 / 2

sin 60 = √3 / 2

tan 60° = √3

Hence,

2 cos 30° + 4 sin 60° + 5 tan 60°

= 2 × √3/2 + 4 × √3/2 + 5√3

= √3 + 2√3 + 5√3 ( ∵ 2 's are cancelled )

= 6√3 is the answer.
