Question

2. (Sin 30°+COS 60°)-(sin 60° + COS
30°) is equal to:​

Answer 1

Answer:

=> (Sin 30°+COS 60°)-(sin 60° + COS30°)

=> sin30°+ cos60°-sin60°-cos30°

$\frac{1}{2} + \frac{1}{2} - \frac{ \sqrt{3} }{2} - \frac{ \sqrt{3} }{2}$

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