Question 1208265
<pre>
I will assume y and 2x are measures in degrees of 2 vertical angles.

Since vertical angles have equal measures, y = 2x

{{{system(y+x+y+5=180,y=2x)}}}

Substitute 2x for y in the first equation:

{{{2x+x+2x+5=180}}}
{{{5x+5=180}}}
{{{5x=175}}}
{{{x=35^o}}}

y = 2x so

{{{y=2*35^o}}}

{{{y=70^o}}}

x=35<sup>o</sup> and y=70<sup>o</sup>
