To find the value of alpha when sin(α) = 1/2, you can reference the unit circle or trigonometric values. The angles that satisfy this condition are α = 30° (or π/6 radians) and α = 150° (or 5π/6 radians) in the range of 0° to 360° (or 0 to 2π radians). Additionally, the general solutions can be expressed as α = 30° + 360°k and α = 150° + 360°k, where k is any integer.

What is 19sin(50) divided by sin(40)?
To find the value of ( \frac{19 \sin(50^\circ)}{\sin(40^\circ)} ), we can use the sine function values. Using the sine of complementary angles, ( \sin(50^\circ) = \cos(40^\circ) ). Therefore, ( \frac{19 \sin(50^\circ)}{\sin(40^\circ)} = \frac{19 \cos(40^\circ)}{\sin(40^\circ)} = 19 \cot(40^\circ) ). For an exact numerical value, you can compute ( 19 \cot(40^\circ) ) using a calculator.
