This Should Help a Little:
A largely semi-arid belt of barren, sandy and rock-strewn land, the Sahel marks the physical and cultural transition between the continent's more fertile tropical regions to the south and its desert in the north. ... The Sahel also suffers from ethno-religious tensions, political instability, poverty and natural disasters.
Yes it does, it influences climate because of wind direction.
Answer:
you need to include the statements
We know that the sum of the interior angles of every triangle is 180°:
( 15 y + 9° ) + ( 22 y + 8° ) + ( 14 y + 10° ) = 180°
15 y + 22 y + 14 y = 180° - 9 ° - 8° - 10°
51 y = 153°
y = 153° : 51
y = 3°
∠ V = 15 · 3° + 9° = 54°
∠ U = 22 · 3° + 8° = 74°
∠ W = 14 · 3° + 10° = 52°
Let`s assume that opposite the angles V, U and W are sides v , u and w. Opposite the smallest angle is the smallest side of a triangle.
Answer: Side length w is the smallest.
