A store manager created this table representing the relationship between the reported days of an outside temperature of over 80° Fahrenheit during a given month x and and the sales revenue of swimwear y, round it to the nearest dollar.

using the linear best fit model for the data what is the predicted sales revenue of swimwear given 25 days of an outside temperature of over 80° F during the month

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
