Question

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

Answer 1

Answer:

15

Step-by-step explanation:

√3/2×√3/2-1/2×1/2=3/4-1/4=3-1/4=2/4=1/2=sin30=30/2=15

Answer 2

Answer:

sin 2x=sin 60° cos 30°-cos 60°sin 30°

=> sin 2x=sin(60-30)°

=> sin 2x=sin 30°

=> 2x= 30°

=> x=30/2°=15°

value of x= 15°
