The answer is x = 6
To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2
In this problem a = x b = 8 and c = 10
You would then square these numbers
x^2 + 64 = 100
Next, you would subtract 64 from both sides.
x^2 = 36
All that’s left is the find the square root, which is x = 6.
So, therefore, you’re answer is x = 6
i believe its b

Answer:
C = 11.18 D= 20
Step-by-step explanation:
Let's start with C
Square root both areas of the squares
![\sqrt{25} =5](https://tex.z-dn.net/?f=%5Csqrt%7B25%7D%20%3D5)
![\sqrt{100}=10](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D%3D10)
Then use the Pythagoras Theorem: ![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
![10^{2} +5^{2} =125](https://tex.z-dn.net/?f=10%5E%7B2%7D%20%2B5%5E%7B2%7D%20%3D125)
= C
Moving on to D
Square root both areas of the squares
![\sqrt{841} =29](https://tex.z-dn.net/?f=%5Csqrt%7B841%7D%20%3D29)
![\sqrt{441} =21](https://tex.z-dn.net/?f=%5Csqrt%7B441%7D%20%3D21)
29 is the hypotenuse, we are trying to find the other leg, so:
![29^{2} -21^{2} =400](https://tex.z-dn.net/?f=29%5E%7B2%7D%20-21%5E%7B2%7D%20%3D400)
= D
Answer:
C
Step-by-step explanation:
Using PEMDAS we can figure out what to do to simplify this problem.
The "E" in PEMDAS referrers to "Exponents".
Square roots are still exponents, just written weird.
![\sqrt{38} = 38^\frac{1}{2}](https://tex.z-dn.net/?f=%5Csqrt%7B38%7D%20%3D%2038%5E%5Cfrac%7B1%7D%7B2%7D)
So, according to the laws of PEMDAS, we must find the square root of 38 first
![\sqrt{38} = 6.16](https://tex.z-dn.net/?f=%5Csqrt%7B38%7D%20%3D%206.16)
Next, we just add 2.
6.16 + 2 = 8.16
Point C is the closest to 8.16
