Question

Find.(Sin 30°+cos 60°)-(sin 60° + cos 30°) is:

1) 1-√3
2) 3
3) 1+2√3
4) 1+√3




PLzzzz Helpppp meeee​

Answer 1

Answer:

1-√3 is absolutely correct answer

Answer 2

Step-by-step explanation:

sin30° = 1/2 and cos60° = 1/2

sin60° = √3/2 and cos30° = √3/2

Now,

(sin30°+cos60°)–(sin60°+cos30°)

$= ( \frac{1}{2} + \frac{1}{2} ) - ( \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} )$

$= 1 - \sqrt{3}$
