Blue Book, p.534 #11

<p>I can't find it in the consolidated list, which probably means I'm a moron but whatever. This obscure problem seems beyond my realm of realization.</p>

<p>Oh come on :D</p>

<p>the angle next to 65 is just 25
therefore it is a vertical angle to the other one
25 + 20 + x = 180
x = uh...... 135 lol as i was thinking i wrote periods.</p>

<p>Pardon? A vertical angle?</p>

<p>Heh, I hope you aren't pulling our leg here, this problem is simple.</p>

<p>The angle to the right of 65 is 25 (90 + 65 + 25 = 180 to make the straight line). After that you can take that 25 and copy it onto the other side (vertically opposite angles). so you're left with all the angles except x, to find x do 360 - (sum of other angles).</p>

<p>Ok, I got it....</p>

<p>The line basically forms a 180 degree angle to line m. 20+25+x=180, x=135, done.</p>
