With two parallel lines and a transversal, an alternate interior angle and a co-interior angle (both measured from the same interior angle on the lower line) are such that the alternate interior angle is 50°. Find the co-interior angle.

Question

Accepted Answer

130. The interior angle on the lower line equals its alternate interior partner = 50°. Its co-interior angle on the upper line = 180 - 50 = 130°.

With two parallel lines and a transversal, an alternate interior angle and a co-interior angle (both measured from the same interior angle on the lower line) are such that the alternate interior angle is 50°.
Find the co-interior angle.
