BD is the angle bisector of ZABC
Thepotemich [5.8K]

Answer:

x = 7, y = 2

Explanation:

Two triangles are said to be congruent if all three sides and three angles of one triangle is equal to three sides and three angles of the other triangle.

From the question:

BD ≅ BD (reflexive property of equality)

Since BD is the angle bisector of ∠ABC, hence ∠ABD = ∠CBD

∠ABD = 2x + y, ∠CBD = 14 + y. Therefore:

2x + y = 14 + y

2x = 14 + y - y

2x = 14

x = 14 / 2

x = 7

Also, ∠BAD = ∠BCD = 90° (right angled triangle)

Since ∠BAD = ∠BCD, BD ≅ BD and ∠ABD = ∠CBD, therefore ΔABD is congruent to ΔCBD by angle-angle-side congruence theorem.

The angle-angle-side congruence theorem states that if two angles and one side of one triangle is equal to two angles and one side of another triangle the both triangles are congruent.

ΔABD is congruent to ΔCBD, therefore AD = CD

5x - y = x + 13y

13y + y = 5x - x

14y = 4x

14y = 4(7)

y = 4(7) / 14

y = 2

Anna35 [415]

The principle of states that the physical, chemical, and biological processes at work shaping the earth today have also operated in the geologic past is uniformitarianism.

<h3>What is biological system?</h3>
  • A biological system is a complex network which connects several biologically relevant entities.
  • Biological organization spans several scales and are determined based different structures depending on what the system is.
  • Examples of biological systems at the macro scale are populations of organisms.
  • On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the nervous system.
  • On the micro to the nanoscopic scale, examples of biological systems are cells, organelles, macromolecular complexes and regulatory pathways.
  • A biological system is not to be confused with a living system, such as a living organism.
<h3>What in nature is biological?</h3>
  • All of the branches of the natural sciences that focus on different facets of life's processes are included in the biological sciences.
  • The notion spans all species, from bacteria to animals and plants, and incorporates anatomy, physiology, cell biology, biochemistry, and biophysics.

Greenhouse gases keep the earth warm through a process called
Yakvenalex [24]

The correct answer is - Greenhouse effect.

The Greenhouse effect is a process in which certain type of gasses in the lower atmosphere manage to trap the heat that is radiated from the surface of the planet.

The gases that are considered to be greenhouse gases are able to perform such a thing, despite being relatively low in amount compared to other gases, because they have much more complex molecular structure.

The molecular structure of this gases enables them to trap the heat, or rather to not allow to leave the atmosphere and return it back toward the surface, thus having huge effect on the climate.

Greenhouse gases are the carbon dioxide, methane, water vapor, nitrous oxide.
