8 5 practice using the law of sines
How do you use the Law of Sines?
The law of sine is explained in detail as follow: In a triangle, side “a” divided by the sine of angle A is equal to the side “b” divided by the sine of angle B is equal to the side “c” divided by the sine of angle C.
In this case, the fraction is interchanged.
It means that Sin A/a, instead of taking a/sin A.Sine Rule.
The Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known.
What is an example of the sine law?
Example: If the side lengths of △ABC are a = 18 and b = 20 with ∠A opposite to 'a' measuring 26º, calculate the measure of ∠B opposite to 'b'? Solution: Using the sine rule, we have sinA/a = sinB/b = sin26º/18 = sin B/20.
How can you apply Law of Sines in real life?
One real-life application of the sine rule is the sine bar, which is used to measure the angle of a tilt in engineering.
Other common examples include measurement of distances in navigation and measurement of the distance between two stars in astronomy.
