Hi there!
Let's use the given formula of a square (A = s^2), to figure out what the equation would be. We are looking for one side, or s here.
WORK:
81 = s^2
squareroot(81) = s
ANSWER:
The second option, root 81.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
Answer:
answer to the second part: A rational number has a finite number of decimal places, but an irrational number decimal places go on forever.
