Question

Cos 30° + sin 60°
1 + sin 30°- cos 60°​

Answer 1

Step-by-step explanation:

cos 30 = root3/2

and sin60 = root3/2

there fore cos30+sin60 = (root3+root3) /2 =2root3/2

root3 is answer

Answer 2

Answer:

2

Step-by-step explanation:

= cos 30 + sin 60 + 1 + sin 30 - cos 60

= cos 30 + cos (90-60 ) + 1 + sin 30 - sin (90-60)

= cos 30 + cos 30 + 1 + sin 30 - sin 30

= 2 cos 30 + 1

Putting in value of cos 30

= 2 (1/2) + 1

= 1 + 1

= 2
