Chapter 7 - Applications of Trigonometry and Vectors - Section 7.1 Oblique Triangles and the Law of Sines - 7.1 Exercises - Page 301: 10

Answer

Not sufficient information

Work Step by Step

The Law of Sines states: $\frac{a}{\sin \angle A}=\frac{b}{\sin \angle B}=\frac{c}{\sin \angle C}$ As we are given $a$, $b$ and $c$, w cannot determine the angles $A$, $B$, $C$ solving the above equations. So there is not sufficient 9information to solve the triangle using the Law of Sines. The Law of Cosines can be applied in this case.
