Is it possible for a cross section of a cube to these shapes....
pentagon
isosceles triangle
scalene triangle
..... If so, please describe how the plane intersects the cube.
Thanks!!!!

If you had a iscocles triangle and the vertex was 21y+13 and the bottom angle which is <b and was 6y+1 what would <a be and what would y be?
