Chapter 8 - 8.1 - Law of Sines - 8.1 Exercise - Page 566: 28

Answer

No Triangle.

Work Step by Step

Note: The Law of Sines is: $\frac{a}{sin(A)}$ = $\frac{b}{sin(B)}$ = $\frac{c}{sin(C)}$ Note: The domain of sine is -1 $\leq$ sin(x) $\leq$ 1. To solve the triangle, we need to find B, C, and c. Finding B: We can use the Law of Sines. $\frac{4.5}{sin(58^{o})} = \frac{12.8}{sin(B)}$ Therefore, sin(B) = 2.412 Since 2.412 is not in the domain of sine, there is no triangle.
