Answer:
<h2><u><em>
nonagon, 9 sides</em></u></h2>
Step-by-step explanation:
the interior angles is 360 - 220 = 140°
it's a<u><em> nonagon, 9 sides</em></u>

Answer:
5 - 8 = -3
4 x -3 = -12
2 + -12 = -10
Step-by-step explanation:
Answer:
58 degrees
Step-by-step explanation:
In a rectangle, the two diagonals form four isosceles triangles. This means triangle EBC is isosceles. In an isosceles triangle, the two base angles are the same. So, angles EBC and BCE are both 61. Now, in a triangle, the three angles add up to 180. So, 61+61=122, and to find angle CEB you need to subtract 180-122. 180-122=58 degrees.
I am assuming you want to find r. r = -36
Answer:
2/3=4/6 and that's 4 times 1/6. So the answer is 100% times 4 which is 400%
