<p>I cant draw the triangle, so if you guys would be kind enough to see the problem if you have the blue book 2nd edition. Practice test 4, section 6, number 15. Can someone explain to me how to get to the answer.</p>
<p>The first step is to find the base and height of each triangle. The bases (PT and PR) are 3 and 4. The height of the large triangle is QV; 3. Since QS is 1, SV must be 2 (Segment Addition Postulate). Now you just use 1/2<em>b</em>h to find the area of each triangle, then divide them to find the answer.</p>
<p>omg…i did such a silly mistake, i kept making SV equal 3 lol. Thanks for clearing things up!</p>
<p>hey kestreal can you help me out on number 18 on that same section. I know how to get it because of college boards explanation, but i would like to see if theres a different way to doing it.</p>
<p>Hm…I can’t think of a method other than CB’s explanation of subtracting 2*4! from 5!. Maybe someone else can think of a way.</p>
<p>alrights its ok, thanks anyways</p>
