C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.

A non-regular hexagon has a five exterior angle measures of 55, 60, 69, 57, and 57. What is the measure of the interior angle ad
kompoz [17]
<span>the 6 exterior measures = a, b, c, d, e, f. 
Their sum is 360 degrees. 
For each one, the interior angle = 180 - exterior. 

So for your problem, 
a = 55, b = 60, c = 69, d = 57, 
e = (missing one) 
f = (remaining one, not given). 

Take 55 + 60 + 69 + 57 + e, subtract from 360 to get f. 
f = 119 - e. 

Then the interior angles are: 
125, 120, 111, 123, (180 - e), and (180 - 119 + e) = (61 + e).</span>

1. To find the square root, you have to square root them both.

Square root of 324 is 18, so x=-18, 1818

2. Divide 49 by 9. 49/9=5.44 then find the square root of 5.44 which is 2.3, x=-2.3, 2.3.

3. To do this one it is one of either 2 or 4 because it is not a perfect square, it can break down to square root of 16 and square root of 6, which then makes it +-4 square root 6.

4. This one is simple the square root of 34 is 5.8

5. Subtract each by 5 to get 6y^2=215 then divide each by 6. Y^2=34.8 then square root. Which makes y=+-5.9. Hope this helped.
