In order to find the hypotenuse in a third dimension, you must first find the hypotenuse of the diagonal of a side of the rectangle, not the base. true or false

i belive it is true!

Step-by-step explanation:

False.

Step-by-step explanation:

If you were finding the hypotenuse in a third dimension  of a rectangular prism you'll need to first find the hypotenuse  of the base. This hypotenuse would be the base leg of the right triangle while the other leg would be the height of the prism.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
