Please check the attached picture

Answer 2

Answer:

A) 1

Step-by-step explanation:

Sin 60 = √3/2

Cos 30 =√3/2

so, Sin 60 × Cos 30

= √3/2 × √3/2

= 3/4

Now, Sin 30 = Cos 60 = 1/2

SO, sin 30 × Cos 60

= 1/2 x 1/2

= 1/4

Final Step:

Sin 60 . Cos 30 + Sin 30 . Cos 60

= 3/4 + 1/4

=4/4

= 1 ( ANSWER)
