The product of sin 30° and sin 60° is same as the product blank of

and blank

A. cos 60 degrees

B. tan 30 degrees

A. cos 30 degrees

B. tan 60 degrees

A. cos60° and A. cos30°

Step-by-step explanation:

We know that is A and B are complementary, so

sinA = cosB

sin30° = cos60° and

sin60° = cos30°

So,

sin30°·sin60° = cos60°·cos30°

The product of sin30° and sin60° is same as the product of cos60° and cos30°.

A. & A.

Step-by-step explanation:

sin (x) = cos (90-x)

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

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