Answer:
From the triangles, I think the congruence statement would be that of the ASA theorem. Triangle AWC is congruent to triangle RWC by virtue of the Angle-Side-Angle theorem. hope I helped ;)
Explanation:
Answer:
Fossils
Explanation:
Because most fossils are a hundred, thousand years old, even a million years old...65 million years, that is for the fossils of dinosaurs
It's a,b, and e (earthquakes, formation of new crust, volcanism)
<h3>As we know that sum of three angles of triangle is 180º.</h3>
we have
<h3>
The angles a and c are equal so,</h3>
- cb = ab. [ sides opp to equal angles are equal]
so x is also 16
<h3>
Now we have two side we can easily find the third side by P.G.T</h3>
<h3>so the r is root 512 and x is 16.</h3>
Hope it helpa
Answer:
As rocks on the earth go through various cycles, similarly the variation in chemical take place.
Explanation:
- As there exists a difference in the composition of minerals chemical composition from there pure forms, some variation exists in the chemical composition of elements like the size of irons, ad the temperatures at which the crystal grows.
- As rocks are an aggregate of more than one mineral they have distinct qualities like the granite is defined by the by proportions of quartz, and feldspar. Like the coal is a sedimentary rock being composed of carbon.
- The presence of oxygen, silicon, magnesium, calcium, and sodium in rocks defines their constituents, as by far Oxygen and Silicon is two of the most dominant 47% and 28%.
- An example of chemical alteration on earth is the volcanic rocks that are both igneous and metamorphic Depending on the chemical properties of these rocks the various metallic nature of elements the rocks have different temperatures and magnitudes.
