Answer:
Step-by-step explanation:
The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.
DG*DE/2 = GE * DF/2            Multiply both sides by 2
DG*DE = GE * DF
DG = 8
DE = 15
GE = 17
8*15 = 17* DF
120 = 17 * DF                         Divide by 17
120/17 = DF
DF = 7.06

Answer:
384 Cubic Inches
Step-by-step explanation:
We can divide the original object into two separate shapes, then we can take the first shape of 6*4*2, and find its volume of 48, then we can take the larger object of 12 * 14 * 2 and find its volume of 336 and add the two values together to find the original shape's volume of 384 Cubic Inches.
 
        
             
        
        
        
55-24=31
31/55=56%
55 > 31 so decreased
Percent of change is decrease 56%
