The third angle is 105. How do I know this? Add 22 and 53: 22 + 53 = 75 All interior angles on a triangle should add up to 180. Subtract 75 from 180: 180 - 75 = 105 105 is our answer. Hope this helps! =)
Hi, i hope this helps! The coordinates are (6,6). I figured this out by plotting the given points and remembering that a rectangle has parallel sides and right angles :))
