Question

evaluate the following :
sin 60 degree cos 30 degree + sin30degree cos60degree
​

Answer 1

Step-by-step explanation:

choose any one of them and write

Answer 2

sin 60° = root 3 / 2

cos 30° =root 3 / 2

sin 30 = 1/ 2

cos 60 = 1/ 2

so root 3/2 ×root 3/ 2 + 1/2 × 1/2

3/4/+ 1/4 = 4/4 = 1
