If an exterior angle of a triangle is 130° and one of the interior opposite angleis
the other interior opposite angle.
nd the interior opposi​

Answer 1

sum of exterior angle in a triangle = sum of two interior angles in a triangle.

so,

130 = 60 + X

X = 130-60

X = 70°

therefore the interior opposite angle is 70°.
