Question:

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.

$$B = 104{}^\circ, \quad a = 11 \text{ cm}, \quad c = 18 \text{ cm}$$

Solution:

$$Area = \frac{a * c * \sin B}{2}$$

where $b, c$ are the two known sides and $B$ is the included angle.

$$Area = 11 * 18 * \sin(104{}^\circ)/2 = 96.06 \text{ cm}^2.$$
