State whether the given statement is true or false.
Answer to Problem 9SGR
False
Explanation of Solution
Given :
The Law of Sines can be used to find an angle measure when given three side lengths.
Calculation:
Law of Cosine:
Law of Sine:
So, if the three sides are known , first , we have to use the Law of Cosine to determine one angle and then we can use the Law of Sines to find other two
Hence , the statement is false.
The correct statement is :
The Law of Cosines can be used to find an angle measure when given three side lengths.
