Answer 2

1. A triangular section of a lawn will be converted to river rock instead of grass. Maurice insists that the only way to find a missing side length is to use the Law of Cosines. Johanna exclaims that only the Law of Sines will be useful. Describe a scenario where Maurice is correct, a scenario where Johanna is correct, and a scenario where both laws are able to be used. Use complete sentences and example measurements when necessary.

Answer 5

@mathmale help?

Answer 6

The Law of Sines cannot be used unless you to know one of the angles AND the length of the side opposite that angle. Once you know that, information about any other angle or side will allow you to find the rest of the missing information about the triangle.

The Law of Cosines can be used when you know either 1) All three side lengths, or 2) One angle and any two sides.

So:

- both laws can be used when you know one angle and the side opposite it, plus one other side
- only the law of Sines can be used if you know one side, the angle opposite it, and one other angle
- only the law of Cosines can be used if you do NOT know the length of a side opposite an angle that you know.
