Yes. Combined, they would form a straight line, or 180 degrees.

The measures of two adjacent interior angles sum to 180 because they form a linear pair.B. False
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

False*APEX*
Yes
No. 360 degrees is a full circle. These two angles, when added together would form a straight line, or 180 degrees.
only in a parallelogram
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line
