There are 180° in a triangle and a straight angle.
You start by subtracting 180-127 to get the angle opposite to the 127 degree angle. This is 53 degrees. Then you subtract the total amount of degrees by adding the two known angles 65+53 and subtracting them by 180. You do this to find the last angle. 180-118=62. x=62°
All of the angles are different so it is a scalene triangle.
