Question

What is the exact value of sin 30° ?

Answer 1

From the equilateral (60-60-60) triangle with all legs of length 1, we can view half the triangle, forming a 30-60-90 triangle, with the hypotenuse measuring 1, the short leg1/2, and the long leg 3 2. Therefore, we have sin 30° = 1/2, cos 30° = 3 2, sin 60° = 3 2 and cos 60° = 1/2.

i hope this help

Answer 2
