One side is 6 cm the other is 11 cm
A=23 cm ^2
a) Solve the Angle between the sides
b) Solve the rest angles and sides
$\displaystyle b=6$ and $\displaystyle c=11$.
$\displaystyle A$ is the angle between b and c.
$\displaystyle \Delta$ is the area of the triangle.
$\displaystyle \Delta=\frac{1}{2}bc\cdot \sin{A}$
$\displaystyle 23=\frac{1}{2}\times 6\times 11\times \sin{A}$
Solve for A
