It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
First take the square root of 25, then take the square root of 49.
It is as easy as separating the square root to apply to both terms separately instead of combined.
sqrt(25)/sqrt(49)
5/7

Answer: </h3><h3>
x = 58</h3><h3>
y = 32</h3>
=============================================
Explanation:
If angle x is the reference angle, then the side 9 is the adjacent side (it is the closer leg to angle x). The hypotenuse is 17 as it is opposite the largest angle. The largest side is always opposite the largest angle in a triangle.
-----------------
cos(angle) = adjacent/hypotenuse
cos(x) = 9/17
x = arccos(9/17)
x = 58.034281249203
x = 58
Arccosine is the same as inverse cosine, written as ![\cos^{-1}](https://tex.z-dn.net/?f=%5Ccos%5E%7B-1%7D)
Make sure your calculator is in degree mode.

Edit:
After finding x, we can find y
x+y = 90
58+y = 90
y = 90-58
y = 32
The answer's 22.4. You have to divide 548.8 miles by 24.5 gallons.
