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:
The Portuguese, French, British and Dutch
Explanation:
While it was the Portuguese who pioneered the earliest ventures of Europeans into Africa, they were soon followed by others. Most of the European outposts along the coast changed hands from time to time as the relative power and influence of different players waxed and waned. The French, British, and Dutch were all major players, and much of the most lucrative trade was based on the trans-Atlantic slave trade. European ships established a ‘triangular’ trading route, bringing goods for trade from Europe to the West coast of Africa, then taking slaves across to the New World, and returning to Europe with agricultural commodities from there.
