Answer:
X = √1252 = 2√313 ≈ 35.384
Step-by-step explanation:
Every number has a square root. If the number is not a perfect square, then that square root is irrational. (If the number is negative or complex, the square root is complex.)
Your scientific calculator can tell you what the approximate decimal value of the square root of 1252 is.
You will recognize that it is an even number, and that it is divisible by 4. This means the square root can be simplified a little bit.
![X=\sqrt{1252}=\sqrt{2^2\cdot 313}=\sqrt{2^2}\sqrt{313}\\\\X=2\sqrt{313}](https://tex.z-dn.net/?f=X%3D%5Csqrt%7B1252%7D%3D%5Csqrt%7B2%5E2%5Ccdot%20313%7D%3D%5Csqrt%7B2%5E2%7D%5Csqrt%7B313%7D%5C%5C%5C%5CX%3D2%5Csqrt%7B313%7D)

<em>Comment on your numbers</em>
The numbers 24 and 26 suggest that perhaps X has a different value. The triple (5, 12, 13) is a fairly common Pythagorean triple, so we might expect you to be seeing the numbers (10, 24, 26), which are double those values. In the formula c² = a² + b², that would make 26 = c.
What is always true is that the sum of the squares of the sides is equal to the square of the hypotenuse. The designations of a, b, c don't always correspond to sides and hypotenuse in that order. In any given problem, they may be mixed up. Check the diagram.
The closeness of the scores to the mean value is reflected through the values of the standard deviation. The smaller the value of standard deviation, the closer are the individual values to the mean. Therefore, since Mrs. Rijo's class has the smallest value for the standard deviation, her class has the closest individual score to the mean. The answer is the fourth choice.

Answer:
Step-by-step explanation:
1. <u>Use the formula below to find the sum of interior angles of the regular polygon:</u>
<u>Applying to hexagon:</u>
- S = 180°(6 - 2) = 180°(4) = 720°
Correct option is C
2. <u>Sum of the angles of the given hexagon:</u>
- 94° + 167° + 98° + 122° + 132° + x = 720°
- 613° + x = 720°
- x = 720° - 633°
- x = 107°
Correct option is C
