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
<u>Iron-rich minerals align with the Earth's magnetic field</u> as basaltic lava erupts, cools, and forms magnetic patterns on the seabed.
Lava is molten rock that emerges as a liquid from under the Earth's surface. The term "lava" is also used to describe the rock that is generated when molten lava cools and solidifies. Either the substance is exceedingly stiff and barely flows, or it might be incredibly fluid, flowing nearly like syrup. The viscosity of the lava increases with silica concentration.
Hawaiian terms pahoehoe and aa (or a'a) refer to flows that are often formed by mafic (ferromagnesian, dark-colored) lavas like basalt. Smooth, subtly undulating, or extensively hummocky surfaces define Pahoehoe lava flows. A thin, still-plastic crust is dragged and wrinkled into twisted rope-like folds and rolls by the flowing molten lava beneath it.
