<p>How was the trapezoid could not be determined??? ughh</p>

<p>Confirm/deny the trapezoid question, was it the 180-measure or was it can not be determined</p>

<p>The one with the Triangle with the V was 15 right?</p>

<p>what was the trapezoid question I don’t remember.</p>

<p>For the area of the triangle in the rectangle the answer was 25.</p>

<p>Guys, for grid in answers, if you have a fraction that can be reduced, do you still get credit? I said 30/9 instead of 3.33</p>

<p>Kevin, I could’ve sworn that the question said that 65 were left…not 63</p>

<p>I think trapezoid was in fact 105 degrees for x
because if you draw a right triangle on the left side of the trapezoid (creating a triangle with angles of 75, 15, and 90 degrees) you will see that the top angle is 15 degrees.</p>

<p>15 + 90 = 105 </p>

<p>you get the 90 from the right angle formed when drawing your triangle</p>

<p>For the 3.33 one is it okay to have put 3.3??</p>

<p>(9,6) (0,0) (5,3.33) for the missing point?</p>

<p>@Skorpius7, I can confirm it is 63. 100% certain.</p>

<p>Actually, since the top and bottom are parallel, the side acts as a transversal, therefore the two angles must add to 180</p>

<p>the trapezoid question could be determined. it was 105 (180-75)
the angles on the other side do not matter because they only affect each other, not the ones on the side we care about</p>

<p>I’m quite certain that the definition of a trapezoid is: “A quadrilateral with only one pair of parallel sides”. The top and bottom were parallel, therefore they add to 180 to make a line. Anyone agree?</p>

<p>the trapezoid one I put 105.</p>

<p>trapezoid definitely 105.</p>

<p>@skorpius 99% it was 63 remaining
@brolex sorry, i think they mark 3.3 incorrect since it is not the full answer, kind of bs though</p>

<p>I also got 180-n for the trapezoid question.</p>

<p>Because you dont know the relationship between the non-parallel sides of the trapezoid. The ONLY requirement of a Trapezoid is to have two parallel sides.</p>

<p>Would 33 work as answer for the multiples of 3?</p>

<ul>
<li>3 omitted 3…shoot</li>
</ul>

<p>skorpius I think you’re overthinking the trapezoid problem…</p>
