Suppose you are offered just one slice from a round pizza (in other words, a sector of a circle). the slice must have a perimeter of 32 inches. what diameter pizza will reward you with the largest slice? specify the diameter and the maximum area of the slice.

Dimeter is 28inch and area is equal to 26.7inch^2

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
