Answer 1

Answer:

1

Step-by-step explanation:

Sin60° cos30°+sin30° cos60°

(√3/2) (√3/2) +(1/2) (1/2)

(3/4)+(1/4)

(4/4)

1

sin60°=√3/2

sin30°=1/2

cos60°=1/2

cos30°=√3/2

Answer 2

Answer:

sin 60 =  √3/2 = cos 30

sin 30 = 1/2 = cos 60

hence,

=>  (√3/2) ×( √3/2)+( (1/2)× (1/2))

=> (3/4) + (1/4)

=> (3+1)/4

=> 4/4

=> 1
