Answer: No, Ariel should have added 9^2 and 12^2 and compared that to 15^2.
Explanation:
Ariel completed a work to show that a triangle whether a triangle with side lengths of 9, 15, and 12 form a right triangle.
Ariel added 9 squared + 15 squared = 12 squared. 81 + 225 = 144 and concluded that 306 is not-equal to 144 and hence, it is not a right angle triangle.
To know whether it's a right angle triangle, we had the square of the two lowest figures together if it will be equal to the square of the largest figure which is called the hypotenuse.
9 squared + 12 squared =
81 + 144 = 225
15 squared= 15 × 15 = 225
So it's a right angle triangle since
9^2 + 12^2 = 15^2
Answer:
Amerigo Vespucci is remembered for several important reasons. He explored the mouth of the Amazon River. He also developed a method for determining longitude. Perhaps Vespucci's most important contribution, however, was his realization that the continent he was exploring was not Asia.
En route he discovered what is now known as the Strait of Magellan and became the first European to cross the Pacific Ocean
