Answer:
c) -6
Step-by-step explanation:
50 + 90 + (x+46) = 180 (angle sum property)
186 + x = 180
x = 180 - 186 = -6

The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.
In this case, the equation that fulfills that condition is the first equation (1).
<u>Let’s prove it:</u>
1) ![3w+8-w=4w-2(w-4)](https://tex.z-dn.net/?f=3w%2B8-w%3D4w-2%28w-4%29)
Applying distributive property:
![3w+8-w=4w-2w+8](https://tex.z-dn.net/?f=3w%2B8-w%3D4w-2w%2B8)
Joining together similar terms on both sides of the equality:
![2w+2w-4w=8-8](https://tex.z-dn.net/?f=2w%2B2w-4w%3D8-8)
<h2>
![0=0](https://tex.z-dn.net/?f=0%3D0)
>>>>>>>This is true and fulfills the condition of identity</h2>
The other equations do not fulfill the condition:
2) ![5y+5=5y-6](https://tex.z-dn.net/?f=5y%2B5%3D5y-6)
![5y-5y=-6-5](https://tex.z-dn.net/?f=5y-5y%3D-6-5)
>>>>>>>This is not logic
3) ![6m-6=7m+9-m](https://tex.z-dn.net/?f=6m-6%3D7m%2B9-m)
![6m-7m+m=9+6](https://tex.z-dn.net/?f=6m-7m%2Bm%3D9%2B6)
>>>>>>>This is not logic
4) ![8-(6v+7)=-6v-1](https://tex.z-dn.net/?f=8-%286v%2B7%29%3D-6v-1)
![8-6v-7=-6v-1](https://tex.z-dn.net/?f=8-6v-7%3D-6v-1)
>>>>>>>This is not logic
