If the exterior angle of a triangle measures 130°, then what is the sum of the non-adjacent interior angles of that triangle?

A. 60°

B. 100°

C. 130°

D. 150°

It will be 130

As,

Let, the adjacent angle be a

Then, a=180-130

And Sum of all the three angles of a triangle=180

Then, the sum of other two angles that is non-adjacent angles of a triangle =

180 - (the third angle)

=180 - angle c

=180 - (180-130)

=180-180+130

=130
