Question

evalute sin60°cos30°+sin30°cos60°​

Answer 1

Step-by-step explanation:

Sin 60 = root 3 /2

cos 30 = root 3 /2

sin 30 = 1/2

cos 60 = 1/2

= (root 3 /2 ) (root 3 / 2) + (1/2) (1/2)

= 3/4 + 1/4

= 4/4

= 1

sin 60 + 30 = 90

where sin 90 = 1

Answer 2

Answer:

1

Step-by-step explanation:

It is in the formula of sin(a+b)

sinacosb+cosasinb=sin(a+b)

sin30cos60+cos30sin60=sin(60+30)

=sin90=1.
