Question

(Sin 30°+cos 60°)-(sin 60° + cos 30°) is equal to:

(a)0

(b)1+2√3

(c)1-√3

(d)1+√3

Answer 1

Answer:

answer is ( c )

Step-by-step explanation:

( sin 30⁰ + cos 60⁰ ) - ( sin60⁰ + cos30⁰ )

( 1/2 + 1/2 ) - ( ✓3/2 + ✓3/2 )

( 2/2 ) - ( 2✓3/2 )

( 1 ) - ( ✓3 )

1 - ✓3

hope thus answer is helpful for you

Answer 2

$sin \: 30°= 5$

$cos \: 60°= .5$

$(sin \: 30+ cos \: 60) = 1$

$Sin \: 60=0.86$

$Cos \: 30=0.86$

$(sin \: 60+cos \: 30) \\ \\ =1.36$

$(Sin \: 30+cos \: 60)-(sin \: 60+cos \: 30)$

$= 1-1.36$

$=-0.36$

The answer is A) = 0
