)a rectangular box has length 12 inches, width 20 inches, and a height of 7 inches. find the angle between the diagonal of the box and the diagonal of its base. the angle should be measured in radians.

We assume the base is 12 in × 20 in, so its diagonal has length

... √(12² +20²) = √(144 +400) = √544 = 4√34 . . . inches

Then the tangent of the angle of interest is the ratio of the box height to the base diagonal:

... tan(α) = (7 in)/(4√34 in) ≈ 0.300123

The angle will be the arctangent of this value,

... α = arctan(7/√544) ≈ 0.291569 radians

c - they will have the same distribution

this is the only one that could make sense. : )
