B I’m pretty sure def not A or D lol
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
An autocracy is a system of government in which supreme power is concentrated in the hands of one person, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control (except perhaps for the implicit threat of a coup d'état or mass insurrection).[1] Absolute monarchies (such as Saudi Arabia, the United Arab Emirates, Oman, Brunei and Swaziland) and dictatorships (such as Turkmenistan and North Korea) are the main modern-day forms of autocracy.
In earlier times, the term "autocrat" was coined as a favorable feature of the ruler, having some connection to the concept of "lack of conflicts of interests" as well as an indication of grandeur and power. The Russian Tsar for example was styled, "Autocrat of all the Russians", as late as the early 20th century.
