Pythagorean theorem is

and using that sin is opposite/hypotenuse, you can find the third side of the triangle.

now you know adjacent is 60, so cos=60/61
A box (cube) has all equal edges or sides (s), thus the volume (v) of the cube is:

So since each side or edge around is 3 in, then the length around the square bottom of the box = 4×3 = 12 in
400-5x greater than or equal to 250
-400. -400
———————————————————-
-5x greater than or equal to -250
——. ——
-5. -5
X is less than or equal to 50
*sorry no greater than and equal to key so...
