Question

(Sin 30°+cos 60°)-(sin 60° + cos 30°) is equal to: a)0 (c)1-√3
(d)1+√3a

Answer 1

Answer:

$\: c) \: 1 - \sqrt{3}$

Step-by-step explanation:

$(sin30 {}^{0} + cos30 {}^{0} ) - (sin60 {}^{0} + cos60 {}^{0} )$

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

$= 1 - \sqrt{3}$
