What are the other names of the law of sines?

The other names of the law of sines are sine law, sine rule and sine formula. The law of sine is used to find the unknown angle or the side of an oblique triangle. The oblique triangle is defined as any triangle, which is not a right triangle. The law of sine should work with at least two angles and its respective side measurements at a time.

Is the law of sines obtuse?

But when you apply the Law of Sines, it yields an acute, not an obtuse, angle measurement; and secondly, simply subtracting the (wrong? inaccurate?) acute measurement without taking into account the one given angle measurement seems to violate the rules as well. What's the deal here?

What is 4 times the sine of 105 degrees?

And then to solve for A, we could just multiply both sides times the sine of a 105 degrees. So we get four times the sine of 105 degrees is equal to A. Let's get our calculator out, so four times the sine of 105 gives us, it's approximately equal to, let's just round to the nearest 100th, 3.86. So A is approximately equal to 3.86.

Is 1/4 a sine of 45 degrees over B?

And actually, we could also say, since we could actually do both at the same time, that this is equal to that. That 1/4 is equal to sine of 45 degrees over B. Actually, sine of 45 degrees is another one of those that is easy to jump out of unit circles. You might remember it's square of two over two.
