Quizplus · Accepted Answer

The area of a triangle can be found using the formula $A = \frac{1}{2}bc\sin(A)$, where $A$ is the angle opposite side $a$, and $b$ and $c$ are the lengths of the other two sides. Plugging in the given values, $A = \frac{1}{2} \times 8 \times 15 \times \sin(128^\circ)$, which approximately equals $47.28$ square units.
