Item 6 Find the value of $p$ .

A triangle is drawn. One leg is labeled 12, one leg is labeled 24, and one leg is labeled 21. A segment is drawn from the vertex between the side labeled 12 and the side labeled 24 to the side labeled 21, splitting it into 2 segments, the longer of which is labeled p and is adjacent to the side labeled 24. The two angles formed at the vertex split by the line to the third side are marked as congruent.

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
