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

B

The printing press allowed mass production of books that spread new scientific ideas.
Hi!
There are many causes related to the depletion of rain forests. One would be fires. Another would be trees being cut down almost every year. The main destruction cause would be us humans.
A possible solution for stopping the depletion of rain forests would most probably be to make sure that the animals, plants, and the rain forest itself is healthy. If it is not, there may be serious trouble. Another solution would probably be for us humans to leave the rain forests alone. Alot of fires are caused by us, and chopping down the trees of the rain forest kills the animals, plants, and of course the trees in that rain forest, causing the rain forest to eventually deplete.
Hope this helps, have a wonderful day/night! :)

The salt will wash into the rivers and eventually the ocean. Too much salt in a freshwater system can be deadly to the wildlife. Ultimately, it will end up in the ocean, where it will have negligible impact. The real damage will be to any river systems it's washed into.
