In a right triangle, the hypotenuse has endpoints p(-3,2) and q(1,-3).
if r represents the third vertex in the triangle and r is located in the third quadrant, what is the length of pr?

R has the coordinate (-3, -3)
PR is a vertical line (perpendicular to the X-ray axis)
So it's length is difference between the y coordinates.
PR = √(-3-2)^2=5units

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

The only number less than 8 that can equal 12 would be 6, 36 is the dividend
