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.

Definition of an exterior angle. At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle. See picture below. Calculating the Angles. We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example, x + y + z = 180. We know this is true, because the sum of the angles inside a triangle is always 180 degrees. What is w? We don't know yet. But, we may observe that the measure of angle w plus the measure of angle z = 180 degrees, because they are a pair of supplementary angles.
