All angles of a triangle total to 180 degrees.
It depends on the triangle, whether it's an isoscelese, scalene, equlateral, obtuse, right angle or acute triangle. All the angles have to add up to 180 degres no matter what, so a right angle triangle could be 90, 45 and 45.
55,55, 70 degrees
In a plane (i.e. a sheet of paper) its 180 degrees; on a sphere its always greater than 180.
no it has to snow if its under 32 degres
the location is 55 degres north and 125 degres west
