1andrewalarcon1 · Answer

Polygons usually have angle measures that add up to 360 degrees, and you are given a supplementary angle at the bottom composed of y and 116 which both angle measures add up to 180. So what do you think you should do first? @sibunann

sibunann · Answer

I honestly have no idea. I tried adding up all the angles and finding x from that equaling all the angles to 360 and y came out to be 47 but then once i did x is added up to some wingspanamyame number

whpalmer4 · Answer

the sum of the interior angles of the polygon on the right must be 360 degrees.  

$$125+72+x+y=360$$right?

whpalmer4 · Answer

you also know (or should know) that $$116+x=180$$

sibunann · Answer

so x is 64

whpalmer4 · Answer

solve the second equation for $x$ and substitute it in the first equation.

whpalmer4 · Answer

actually it appears you only need to find $x$ unless there is another part of this problem not shown here.

sibunann · Answer

y= 99 and x=64

sibunann · Answer

i only need to find x

whpalmer4 · Answer

any question about why we could find $x$ this way?
