Arectangle garden is 6 feet long and 4 feet wide a second rectangular garden has dimensions that are doubled the dimensions of the first garden what is the percent of change in the permitter of the first got into the second garden

I do not know this one but the first garden is 24 and the second one is 576.

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
