Question

exterior angle of a triangle is 130 degree and one of the interior opposite angle is 45 degree find the other two angles of a triangle

Answer 1

we can define the angle just next to the exterior as angle1

and the second interior angle  as angle 2

180-130=angle 1 (straight line)

angle 1 = 50 degrees

50 + 45 + angle 2 = 180 (angle sum property)

angle 2 = 180 - 95

angle 2 = 85 degrees

so we go the answer for :

angle 1 as 50 degrees

and

angle 2 as 85 degrees
