Question

the value of (sin 30° + cos 30°) - (sin 60° + cos 60°) ​

Answer 1

Answer:

0

Step-by-step explanation:

(sin30°+cos30°)-(sin 60°+cos 60°)

(cos 90-30+cos30°)-(cos90-60+cos60°)

(cos 60°+cos 30°)-(cos 30°+cos 60°)

cos90°-cos90°

0

Answer 2

Answer:

Answer is 0

Step-by-step explanation:

(sin 30° + cos 30°) - (sin 60° + cos 60°) ------------------ Equation 1

sin 30° = 1/2           cos 30° = $\sqrt{3}$/2

sin 60° = $\sqrt{3}$/2        cos 60° = 1/2

Substituting the values in equation 1 , we get ;

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

(1 + $\sqrt{3}$) /2 - [($\sqrt{3}$ + 1)/2]

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