Question

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 1

I really need help. I already tried but got it wrong

Answer 2

In order for Maurice to be correct, he would need to know at least one angle measure and its side and another side measure. For Law of Sines:\[\frac{ sinA }{ a }=\frac{ sinB }{ b }\]You have to have 3 of the 4 values to make this one work. As for the Law of Cosines, if you were looking for a side length, you would have to know the measures of the other 2 sides and the angle that corresponds to the side you're looking for. Do you have values for any of these sides or angles?

Answer 3

"In order for Maurice to be correct, he would need to know at least one angle measure and its side and another side measure." by its side do you mean and adjacent side or opposite side???
