On a map, 1212 inch represents 4545 mile. what distance on the map represents 1 mile? 2525 in. 5858 in. 135135 in. 212212 in.

First I don’t know if it is a typo or what so im assuming that you are just repeating the numbers. So 12 in represents 45 mile in the map so 1 mile can be calculated by using ratio.

Map distance = 1 mile ( 12 in / 45 mile) = 0.27 inch in the map

my answer is not in your choices, i think, i didnt get your given. so just follow the steps and you will get the correct answer

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
