<p>The question with the 6 angles and one of them being 120 degrees had an answer of 3 angles. 120+90+90=300, which doesn’t leave room for any more right angles.</p>
<p>@AgeOfLox i made the same error…since one of the angles is 120 degrees, the angle exactly opposite of that MUST also be 120. Therefore 120+120=240 and with 120 degrees left (to make 360) no other angles can be right angles (since if an angle was 90 degrees, the vertical angle to it would also have to be 90). So the answer would have to be 4. That question annoyed me.</p>

In case you’re curious about the answer to that math question…
That’s a fun problem…
The area of triangle ABC is 3.</p>
<p>Solution: Draw the circle centered at (2,1) with radius of 2.5 and the two points A (a,3) and B (b,3). Draw segment AB. Since A and B lie on the circle, segments AC and BC are radii, and each have a length of 2.5. Triangle ABC will look like an upside down isosceles triangle. Draw a vertical line segment from C so that it perpendicularly bisects AB at Point D (I assigned this to be point “D” for clarity). The length of CD is 2 (change in the y-coordinate). Coincidentally, drawing CD creates two congruent side-by-side right triangles. Use Pythagorean theorem to solve for the long leg (AD or BD) of either of the right triangles. AB equals 3 (double the length of AD or BD). Use the area formula to solve for the area of triangle ABC.</p>
<p>does anyone remember any of the other answer choices for the question that the confirmed answer is “disparaging”? I just remember the question asked about the tone of the second passage vs. the tone of the first passage.</p>
<p>You should have multiplied the 5% by the 40 students to get the actual amount of students. The graph was only percentages but the question asked for the number of students.</p>
