Question

In a triangle one side is 130 find the other side we an take the other side as x

Answer 1

Answer:

All triangles have 180 degrees total in the interior. The sum of the exterior angles of any figure is 360. A line has 180 degrees. Using this information we take the exterior angle and subtract it from 180 degrees giving us 50 degrees(the interior angle associated with the given exterior angle of 130 degrees). If we add that 50 degrees to the other known angle of 45 degrees we would get 95 degrees. If we subtract that 95 degrees from the total interior angles of a triangle (180 degrees) we would get 85 degrees. Therefore, the two unknown angles are 50 and 85 degrees
