We have two similar triangles.
A ( small ) = 10.5 m²
A ( large ) = 94.5 m²
h ( small ) = ? and h ( large ) = 9 m.
A s : A l = h s² : h l ²
10.5 : 94.5 = h s² : 9²
h s² * 94.5 = 81 * 10.5
94.5 h s² = 850.5
h s² = 850.5 : 94.5
h s² = 9
h s = √ 9
h s = 3 m
Answer: The altitude of the smaller triangle is 3 m.
Answer:
Constructive margins occur when two plates with the same density (continental or oceanic) move away from each other, which causes magma from the mantle to rise to the surface. ... Destructive margins occur when one plate is denser than another and move towards each other.
Answer:
The Great Plains undergo changes from one year to another. These changes are determined by the production of floods, the accumulation of sediments or changes made by man (dams, construction of dams, gravel pits).
The Rocky Mountains shrunk annually. External factors (water, air, wind, freeze-thaw process) cause changes in the structure of the rocks and so there are changes in the mountain landscape.
Some of these are accountable, but the main reason the settlement boom happened is D, gold was discovered.
