4) 19.184 x 0.46 = <span>8.82464
6) 2/11 </span>÷ 3/11 = 22/33 = 2/3
7) 0.58 x 2 = 1.16. 0.58/2 = 0.29. 1.16 + 0.29 = $1.14
A trapezoid has only 1 pair of parallel sides the other 2 sides will join at some point the other 2 sides will never touch so they are parallel.
Hope that helps.
Hello, i am not really good at math but try multiplying...
Option B
The sum of the measures of the exterior angles of a 53 - gon is 360 degrees
<em><u>Solution:</u></em>
The formula for sum of exterior angles "n" is:
![N = 180n-180(n-2)](https://tex.z-dn.net/?f=N%20%3D%20180n-180%28n-2%29)
Distribute 180
![N = 180n - 180n + 360\\\\N = 360](https://tex.z-dn.net/?f=N%20%3D%20180n%20-%20180n%20%2B%20360%5C%5C%5C%5CN%20%3D%20360)
Therefore, sum of measure of exterior angles is 360 degrees
<h3>Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360 degrees</h3>
Thus, in a 53 gon, sum of measure of exterior angles is 360 degrees
