If the numbering of the angles is similar to this:
1 | 2
-----
3 | 4
5 | 6
----
7 | 8
Then none of the the choices are necessarily true.
The equations would have been:
1 = 4 = 5 = 8
2 = 3 = 6 = 7
3 + 5 = 4 + 6 = 180
Multiples of nine: 9<span>,18,27,36,45,54,63,and 72</span>
3w +2 =7w
-3w -3w
2=4w
Divide each side by 4
1/2=w
Check your answer:
3 (1/2) + 2 = 7 (1/2)
(3/2) + (4/2) = (7/2)
(7/2) = (7/2)
Hope this helps.
