Answer 1

Answer:

sin30°=1/2 and cos60°=1/2

Step-by-step explanation:

therfore,1/2+1/2=1

Answer 2

SOLUTION

TO DETERMINE -:

The value of

( sin 30° + cos 30° ) - ( sin 60° + cos 60° )

EVALUATION

( sin 30° + cos 30° ) - ( sin 60° + cos 60° )

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

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