Question

1-(sin 30 degree +co 30 degree)-(sin 60 degree + cos 60 degree) a)-1 b)0 c)1 d) 2​

Answer 1

Step-by-step explanation:

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

= 0

because

sin 30° = 1 / 2

cos 30° = √3 / 2

sin 60° = √3 / 2

cos 60° = = 1 / 2

Answer 2

Step-by-step explanation:

1-((1/2)+(√3/2))-(√3/2+1/2)=-2√3/2=-√3
