Which scenario cannot be modeled by a right triangle? a 13-foot ladder is placed 5 feet away from a wall. the distance from the ground straight up to the top of the wall is 12 feet. wendy leaves school to go home. she walks 60 yards north and then 80 yards west. she is 10 yards from the school. the dimensions of a triangular-shaped garden are 28 yards, 53 yards, and 45 yards. a babylonian writing mentioned a triangle with side lengths 120, 169, and 119.

Bwould be the answer, wendy leaves school

< i think this is the answer unless i did my math wrong

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
