Answer:
676 cubic cm choice d
Step-by-step explanation:
Base area times height gets volume
Base area =  (1/2)*13 * 8  =  52 sq. cm   (area of the right triangle)
height = 13 cm  here
Volume = 13 cm * 52 sq. cm = 676 cubic cm
 
        
             
        
        
        
Answer:
AC Midpoint (2,0)- 
CB Midpoint (5,-4) 
midlength is 5
Step-by-step explanation:
midpoint formula 
A(2,4) C(2,-4)

(2,0)
C(2,-4) B(8,-4)

 midpoint is  (5,-4)
  midpoint is  (5,-4)
Distance between the 2 midpoints is the midsegment
(2,0) and (5,-4)
