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
Answer:1st Big Bang 2nd Sun got borned by millions of tiny stars,space materials all collided together.3rd sun is in our solar system 4th in the future scientists don’t know when but the sun will get bigger swallowing almost all of our solar system (not the universe) and will blow up this is the natural life cycle of the sun predicted
Explanation:
Explanation:
Forest fires make it harder for plants and animals in an ecosystem to grow, this causes a variety of plants in an ecosystem to become extinct in that area, animals have a hard time living in an ecosystem like this and that is why it is harder for biodiversity in an ecosystem happens.
-Hope my answer is helpful!
If I would have the chance to encourage people I would like them to use renewable energies that are good for the environment and enlighten them to use automobiles that respond to this.
Second, I would invite them to get more ideas and do output on recycling used materials that can be found in their garbage.
The correct answer to this open question is the following.
The simple ways you can do or contribute in order to lessen the effect or to fight the natural calamities are the following.
First, Filipino people have to know that mother Earth is a conscious being, like. us. The earth has inner processes to renew itself or to clean itself that have happened since the Earth exists: these are hurricanes, typhoons, tornados, earthquakes, deluges, rains, volcanic explosions, and climate changes.
People have to be aware of this and be prepared. The best form is to have a plan. A prevention plan and an action plan. They have to invest in infrastructure to control and diminish the consequences of natural phenomena. The government has to develop the educational and informative to let people know what to do in the case of these events. Their rescue programs and services have to be well prepared with the proper equipment to act swiftly.
