Use the sine ratio: sine 30 = opposite/12 opposite = 12*sine 30 opposite = 6 inches
sin(30) = 1/2
0.524 or pi/6
sine 810 = sine 90 = 1
mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30
the sine of a 30 degree angle is 0.5

sine of 30 degrees
Use the sine ratio: sine 30 = opposite/12 opposite = 12*sine 30 opposite = 6 inches
sin(30) = 0.5
sin(30) = 1/2
Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
Use the sine ratio: sine 30 degrees = opposite/hypotenuse Then: opposite = 2*sine 30 degrees Answer: 1 foot
Sin30 degrees is 0.50000
Yes, the sine decreases, and so does the tangent.
0.524 or pi/6
Sin(30) + cosec(30) = sin(30) + 1/sin(30) = 0.5 + 1/0.5 = 0.5 + 2 = 2.5
