Need Help, I got two sides and the area in a triangel .. Would be happy for any help!
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

$b=6$ and $c=11$.
$A$ is the angle between b and c.
$\Delta$ is the area of the triangle.

$\Delta=\frac{1}{2}bc\cdot \sin{A}$

$23=\frac{1}{2}\times 6\times 11\times \sin{A}$

Solve for A
