It took 14 bags of sand to fill the small sandbox to the step what volume of sand comes in one bag?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
