Question

the value of sin 60+cos 30 +sin30 cos60=

Answer 1

Answer:

Step-by-step explanation:

sin 60+cos 30 +sin30 cos60

Value of sin60 is 1/√2

Value of cos 30 is √3/2

Value of sin 30 is 1/2

Value of cos 60 is 1/2

To find sin 60+cos 30 +sin30 +cos60

= (√3/2 + 1/√2)  + (1/2 + 1/2)

= (√3+√2+1+1)/2

= (√3+2+√2)2
