Question

sin60° cos30°+ sin30° cos60°​

Answer 1

1

Step-by-step explanation:

Sin60*Cos30+Sin30*Cos60

Sin60*Sin(90-60)+Cos(90-60)*Cos60

Now sin square 60+cos square 60=1

Because sin square +cos square =1

yah hai brainly answer

Answer 2

Step-by-step explanation:

given:-

sin60°cos30°+sin30°cos60°

(√3/2)×(√3/2)+(1/2)×(1/2)

√3×√3/2×2+1/2×2

3/4+1/4

3+1/4

4/4=1

Hence sin60°cos30°+sin30°cos60°=1
