Answer:
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side).
The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
a.
a=3, b=4 and c=5
a² + b² = 3² + 4² = 9 + 16 = 25 and c² = 5² = 25
25 = 25 ⇒ right triangle.
b.
a=5, b=6 and c=7
a² + b² = 5² + 6² = 25 + 36 = 61 and c² = 7² = 49
61 > 49 ⇒ аcute triangle.
c.
a=8, b=9 and c=12
a² + b² = 8² + 9² = 64 + 81 = 145 and c² = 12² = 144
145 > 144 ⇒ аcute triangle.
Explanation:
Mark brainliest please!!
The Earth rumbles and a hiss of steam issues from the top of Mt Ruapehu. Are these two events related? Is the earthquake caused by the volcano? Or is the steam caused by the earthquake?
Tectonic plates
When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’scrust.

<h2>Answer: The Gulf of Mexico
</h2>
The Gulf of Mexico is an ocean basin that formed after the collision of the continental plates and the sinking of the seabed during the rupture of the former Pangea mega continent millions of years ago.
This gulf is also the ninth largest water surface in the world, which is contained among the littorals of Mexico, the United States and the island of Cuba. Therefore, this mass of water corresponds to the Atlantic Ocean in the northern part of the American Continent.
