Web∴ sin 30° = sin(0.5235) = 1/2 or 0.5. Explanation: For sin 30 degrees, the angle 30° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, … WebThe Law of Sines just tells us that the ratio between the sine of an angle, and the side opposite to it, is going to be constant for any of the angles in a triangle. So for example, for this triangle right over here. This is a 30 degree angle, This is a 45 degree angle. They have to add up to 180.

WebExplanation: We know that sin 30° is 1/2. We also know that sin (180° - θ ) = sin θ. sin (150°) = sin (180° - 30°) = sin 30°. So, sin 30° = sin 150° = 1/2. Since angle 30° lies in the first quadrant and angle 150° lies in the second quadrant, therefore the … WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75.
