What is the value of sin 30 degrees?
Answer and explanation
Correct answer: A. 1/2
- Step 1: In a 30-60-90 triangle the side opposite 30 degrees is half the hypotenuse. Step 2. So sin 30 = 1/2. Answer: 1/2. Why not the others: 1: That is sin 90 degrees. root 3 / 2: That is sin 60 degrees. root 2 / 2: That is sin 45 degrees.
