Answer:
x=125º
2x=250º
Step-by-step explanation:
720 is the sum of the interior angles of a Hexagon
720=60+65+120+100+3x
720=345 +3x
-3x=345-720
-3x=-375
-x=-125
x=125
...it is a triangle...if it's asking to prove it's not a certain type of triangle, I can do that, but the only requirement for a triangle to exist is that the 2 shorter sides added together are greater than the longest side.

Answer:
D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin
Step-by-step explanation:
Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a <em>90°-clockwise rotation </em>option, we have to go with something similar to that, which would be a <em>270°-counterclockwise</em> <em>rotation</em><em>.</em><em> </em>If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].
I am delighted to assist you anytime my friend.
