Question

value of sin60°+cos30°​

Answer 1

Step-by-step explanation:

$\sin(60) = \frac{ \sqrt{3} }{ 2} \\ \cos(30) = \frac{ \sqrt{3} }{2} \\ \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} = \frac{2 \sqrt{3} }{2} = \sqrt{3}$

this is you aswer

Answer 2

Answer :

• sin 60° = √3/2
• Cos 30° = √3/2

Value of sin 60° + cos 30°

= √3/2 + √3/2

= (√3 + √3)/2

= 2√3/2

= √3
