Answer : D
Since we know that they are both right triangles, we can automatically assume that the angle measures are going to be 90°,45°,45°.
We can use this information to identify the angle measures of ACB and ABC.
These angles are both located at the 45° positions of the triangle, therefore the both have angle measures of 45°.
There is a wall along it.
Changes in the supply source or sediment supply can begin or end the life of a river.
<h3>What other factors can affect the life of a river?</h3>
Other factors that can affect the life of a river are;
- The kind of rocks present on the shores
- The source and supply of sediments.
Sediments deposited continually on the shores of a river can gradually edge the river away from it's course or cut it off from it's source.
Hence, it is right to state that Changes in the supply source or sediment supply can begin or end the life of a river.

Answer:
Fossil B belongs to the same period as the trilobite.
Explanation:
The Law of Superposition states that the youngest rocks will always be found on top of older rocks. So as you dig deeper and deeper, the rocks you find will be older and older.
An illustration of the problem:
<em>----------------------------------------------------------------------------</em>
Fossil C: Two Semi-circles (<u>Top</u> Layer = <em>Youngest</em>)
-----------------------------------------------------------------------------
Fossil B: Rhombus with Diagnonal & <em>Trilobite</em> (<u>Middle</u> Layer)
------------------------------------------------------------------------------
Fossil A: Shaded Rhomboid (<u>Bottom</u> Layer = <em>Oldest</em>)
So, Fossil A is older than both B and C, or, B and C are both younger than A.
Fossil B is Younger than Fossil A, but older than Fossil C.
Fossil C is the youngest (because its on top).
