What is the percent change of 12 niches to 36 omches

The answer is 200%

Why? --- A change from 12 to 36 represents a positive change (increase) of 200%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = [(12 - 36) / 12] x 100 = 200 % (increase)

Where: 12 is the old value and 36 is the new value. In this case we have a positive change (increase) of 200 percent because the new value is greater than the old value.

Hope this helps. :)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
