The volume of the polyhedron is _ yd3.

122,850 yd³

Step-by-step explanation:

The polyhedron is a right triangle prism

Area of the right triangle prism = ½*a*c*h

a = 91 yd

c = 60 yd

h = 45 yd

Volume = ½*91*60*45

= 122,850 yd³

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
