For the second row i think it should be 2 + y = 5 because 2 x 1 equals 2
Answer:
Given information: WY=ZX, A is the midpoint of WY and A is the midpoint of ZX.
To prove : WA =ZA
Proof:
A is the midpoint of WY, it means A divides WY in two equal parts.
![WA=AY](https://tex.z-dn.net/?f=WA%3DAY)
So, WY is twice of WA.
.... (1)
A is the midpoint of ZX, it means A divides ZX in two equal parts.
![ZA=AX](https://tex.z-dn.net/?f=ZA%3DAX)
So, ZX is twice of ZA.
... (2)
(Given)
Substitute the values from equation (1) and (2).
![2WA=2ZA](https://tex.z-dn.net/?f=2WA%3D2ZA)
Divide both sides by 2.
![WA=ZA](https://tex.z-dn.net/?f=WA%3DZA)
Hence proved.
Without rounding, I make it six. You could do it this way
54527/5^6 comes to a little over 3. That should be close enough. I'm going to check this by doing the divisions. I could let the computer do it, but I'd like to see if there's a pattern. There isn't and the correct answer is
6 <<<< divisions.
Since there is a 180 degrees in a straight line and we know that the intersection of one angle is 27 degrees we can can say 180 -27 = 153 degrees. So the four angles would be 27, 27 153, 153
