if m<1=140, what is m<3?
50 is the correct answer When you have an external angle the two interior angle on the opposite side of the triangle add up to the external angle.So 140 = 90 + x50 =x is correct
Angle 1 = 90 + Angle 3 Exterior angle = sum of opposite interior angles in a triangle.Angle 1 = 90 + Angle 3140 = 90 + Angle 3Angle 3 = 140 - 90 = 50Angle 3 = 50
