Sprinkle this mixture over your carpet. Then, mix 1 quart of warm water with 1 cup of white vinegar. Dip a sponge mop into the vinegar and water, then gently scrub the carpet you sprinkled with the borax and soda earlier. Allow your carpet to dry thoroughly (at least an hour), then vacuum. 6.. Salt. Mixing salt with vinegar works well as a spot cleaner on your carpet, too. Mix these substances to make a paste, work it into the spot, let it soak, then rub the area with a cloth dipped in water or club soda.
The three interior angles of this type of triangle are all 60 degrees, by definition. Therefore, the exterior angles are the supplements of that, or: 180 - 60, which is: 120 degrees. Here is another reference: http://mathforum.org/~sanders/geometry/GP06AnglesPolygon.html. Let me know if you have any questions. If not, please press Accept. Thanks!-Scott
This means that the triangles are all identical, and are the angles (or the triangle) adjacent to the side of the octagon are equal. Since the sum of the angles of a triangle is 180 degrees, each of them measures (180-45)/2 degrees. Since each interior angle of the octagon is comprised of two angles whose measure we just calculated above, each of them measures 180-45 = 135 degrees. It looks as if elbow pieces that measure 45 degrees won't work.
