isosceles triangle height and base given only angles and area If we know only that:
$A=22$
$v_1=30^\circ$ and $v_2=75^\circ$ and $v_3=75^\circ$
How do I get height and base without knowing at least one of the sides?
Edit: v are angles and A is the area.

Hint:  Bisect the $30^\circ $ angle to give two $15-75-90$ triangles.  Use trig to find the relationship between the base and the altitude, then between the base and the area.  Given the area you can compute the base.
