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

Earth is a large spherical landmass, which is divided into three major layers, known as crust, mantle, and core. The innermost layer of the Earth is the core.
<h3>What is the core?</h3><h3 />
- The core of the Earth is the innermost layer, present beneath the mantle and crust.
- The core is entirely made up of iron and nickel. The core of the Earth is also called NIFE, which symbolizes the elements present in the core, Iron (Fe) and Nickel (Ni).
- Core has a radius of approximately 1220 kilometers and is responsible for the generation of the magnetic field.
- Core also consists of the earliest history of the planet and is extremely hot, such that the temperature is close to the Sun's temperature.
Thus, the correct answer is Option D.
