The correct statements among the options are:
- Angle BCE is supplementary to angle ACE.
- Angle BCD is supplementary to angle BCE.
- Angle BCD is congruent to angle ACE
<h3>What are supplementary angles?</h3>
Supplementary angles are known to be angles whose angles are known to sum up to 180 degrees.
Congruent angles are said to be two or more angles that are seen as identical to one another and one can say that they often measure in terms of their angles to each other.

Answer:
Lead is one of the important elements found on earth. They are metallic gray in color and one of the heavy metal. It has a density of about 11.34 g/cm³. It has a high density because of its closed type of packing and face-centered cubic structure. Lead rarely occurs in its pure form on earth. It is mostly found to be present in association with its principle ore known as galena.
Thus, <u>lead is a very denser element as it has a very high density</u>.
<u>In a situation where there is a huge amount of lead in the earth's interior, the lead will be most likely to be found in the core of the earth</u>. It is because, in the present scenario, the core of the earth is comprised of denser elements namely iron (Fe) and nickel (Ni) that have an extremely high density.
Answer: B) Turbidity currents
Explanation: Turbidity currents are large scale water movements which picks and carries different particles in the form of sand,rocks,minerals and other materials which are poorly sorted as it flows to the point of depositon.Turbidity currents contain particles of different sizes, types and shapes as it flow,as it picks larger particles it's speed continue to Turbidity currents are caused my geological movements, earthquakes and cracked slopes. Other options don't carry as much variety of materials as Turbidity currents.
You need to add x1 and x2 then divide by two, then add y1 and y2
