Answer 1

Cos 60 degrees and cos 30 degrees

Explanation:

For edmentum students I got it correct

Answer 2

Explanation:

`sin \: 30 \degree * sin \: 60 \degree \\ = (1)/(2) * ( √(3) )/(2) \\ = ( √(3) )/(4) \\ \\ cos \: 30 \degree * cos \: 60 \degree \\ = ( √(3) )/(2) * (1)/(2) \\ = ( √(3) )/(4) \\ \\ thus \:\\ sin \: 30 \degree * sin \: 60 \degree = cos \: 60 \degree * cos \: 30 \degree \\`

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