<p>What you just need to know is that the tangent line to a circle is perpendicular to the radius that touches the point of tangency. No if’s, and’s, or but’s. That’s just the rule.</p>
<p>im saying isnt the question sorta ambiguous tho? I know it was 90 degrees but I was thinking angle ABO could be 270 if you went the other way around…</p>
<p>It’s a fundamental rule in math to use only smaller value. It’s like walking around the world to get to your neighbor’s house. Technically speaking, it’s definitely a possibility but it’s just not realistic. Don’t get too technical on the SAT; I learned that the hard way :x</p>
