<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.
Answer:
87 is the number
Step-by-step explanation:
Answer:
-20
Step-by-step explanation:
Do the math in the parenthesis first
(5-21) = -16
(3+1) = 4
Rewrite the problem
- 16 - 4= -20
The answer is -20
