<p>I've been reading this over and over again and i'm convinced that the collegeboard made a mistake on their practice SAT test. Please someone help me...</p>

<p><a href="https://docs.google.com/leaf?id=0B9HEAcb-xEIOY2JmZWY3ZGEtYjkxMS00ZjMxLWEwZTctZTQ5OWRlYzNmNzk5&hl=en_US%5B/url%5D"&gt;https://docs.google.com/leaf?id=0B9HEAcb-xEIOY2JmZWY3ZGEtYjkxMS00ZjMxLWEwZTctZTQ5OWRlYzNmNzk5&hl=en_US&lt;/a&gt;&lt;/p>

<p>The answer key says the answer is E but i don't think the answer is there at all... someone please please help</p>

<p>You’re right. Any two such angles are equal or add to 180. Since x and z are not equal, x+z=180. This answer is not there.</p>

<p>the answer is 180 degrees</p>
