Angle 1 is an obtuse(greater than 90 degrees) and angle 2 is an acute(less than 90 degrees) and as they are both on the same straight line they add up to equal 180 degrees.
ahhhh ok. u didnt state that. They are together suplimentary(two angles whose sum makes up a 180 degree angle) Complimentary is when the sum of two angles make up a 90 degree angle.
