The value of A for which the equation; sin A = 2 sin 30° cos 30° is true is; A = 60°

Trigonometric identities

Recall from trigonometric identities that;

  • Sin (2x) = 2 sinx cosx

By comparison with the given equation;

We can conclude that; A = 2x.

And from comparison; x = 30°.

Ultimately, the value of A = 2 × 30° = 60°
