Which of the following numbers could be the sides of a right triangle. a)8,15,17. b)6,8,12 c)9,11,21 d)4,13,16

A) 8, 15, 17.

Step-by-step explanation:

Right triangle obey the Pythagorean theorem. Thus, we choose the two smaller numbers (being the cathetus) and if after applying the P. Theorem we get the biggest of each option  (the hypotenuse) that means that those numbers could be the sides of a right triangle.

The Pythagorean theorem states that:

Thus:

Option A:

→ 17 = 17 OK!

Option B:

→ 10 ≠ 12 NO

Option C:

" alt="\sqrt{202}" />" /> → ≠ 21 NO

Option D:

→ ≠ 16 NO

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!
