We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,
mACE = mECD
Next, we look at the choices
<span>mECD = mECB > This not possible since ray CD is between the two angles
mACE = mACD > This is still not possible since ray CE is between the two angles
mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.
mECD = mACD > This is not possible since ray CE is between the two rays
The answer is the third option</span><span />
Answer:
2.
Step-by-step explanation:
Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.
This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.
hope that answers ur question :))))
Answer:
V = 32 pi
Step-by-step explanation:
The volume of a cone is
V = 1/3 pi r^2 h
The radius is d/2 = 8/2 = 4
V = 1/3 pi (4)^2 * 6
V = 32 pi
