Julie's family is filling up the pool in her backyard the equation Y =5.2 X +8400 can be used to show the rate at which the pool is filling up with water where why is the total amount of water gallons and X is the amount of time minutes how are neighbor Alina is also filling up their pools as Shown in the table. below who's pool is filling up at a faster rate and how do you know.?

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
