Question

22. Find the value of x in the following equation:
sin 2x = sin 60° cos 30° - cos 60° sin 30°​

Answer 1

Answer:

Step-by-step explanation:

sin 2 x=√3/2*√3/2-1/2*1/2

          =3/4-1/4

           =2/4

            =1/2

We know, sin 30 = 1/2

i.e. 2x = 30

x = 15

Answer 2

Answer:

2x=3/4-1/4

2x=2/4

hence ......X=1/4...... hope this help
