Answer:
Geologically, rivers, mountains, oceans, seas, biomes.
Answer: Big boulders are found in the headland because deposition is occurring in this area.
Explanation:
Erosion can be defined as the loss of top most fertile layer of the soil due to the action of the agents like water and wind. The coastal area is prone to erosion due to high water tides and strong wind currents. Boulder beaches are created due to erosion in the coastal area. The erosion and sedimentation of the bedrock and sediments left on the shore due to upwelling of oceanic water are the common causes of development of boulders.
Since the proof for x = 30, the missing reason in step 3 is known to be angle addition postulate.
<h3>What is angle addition postulate?</h3>
This is known to be the law that state that when one put two or more angles side by side making them to share a common vertex and also an arm between the both pair of angles, then the sum of those angles will then be the same with the total sum of the resulting angle.
Since T = is the interior of straight angle ∠VRS.
m∠VRS = 180° ( is a straight line angle)
So, based on the angle addition postulate says that:
m∠TRS + m∠TRV = 180°.
Therefore, since the proof for x = 30, the missing reason in step 3 is angle addition postulate.
