Answer:
XY=8
Step-by-step explanation:
In △XYZ, XY=XZ
It is isosceles triangle whose equal sides are XY=XZ
We are given,
XY=2a
YZ=3a+1
XZ=5a-12
XY=XZ
So, 2a=5a-12
Solve for a,
2a-5a=-12
-3a=-12
a=4
Now we put a=4 into XY=2a
So, XY=2(4)=8
14.7 mm is the height.
Use the volume equation for a cylinder which is
volume=(PI/4)*(diameter^2)*(height)
And you have volume, and diameter (which is just radius times 2) so solve for height.
5588=(PI/4)*(22^2)*Height
Height = 14.7 mm

Answer:
quadrilateral DEFG is reflected to form a quadrilateral D'E'F'G'
Step-by-step explanation:
Vertices DEFG are in a clockwise orientation. Those in D'E'F'G' are in a counterclockwise orientation. The only way vertex order is reversed is through reflection. Translation, rotation, or dilation will not do that.
quadrilateral DEFG is reflected to form quadrilateral D'E'F'G'
