Respuesta :
( B) ∠OSN is the correct answer.
As we know two angles are Supplementary if sum of that two angles is 180° or they form a linear pair
The meaning of linear pair is that the two angles should be such that the non common arms should lie on opposite side of the common arm and at the point of intersection of two angles have the same vertex. Also the two non common arms should form a line.
SO IF ONE ∠ IS Ф° OTHER SHOULD BE 180-Ф°. FOR EXAMPLE ON ∠ IS 60° OTHER WILL BE 180-60°=120°
Supplement of
1.45°=135°
2.70°=110°

<OSN angle is supplementary.
Further Explanation:
<OSN:
Nearby points are two edges that have a typical vertex and a typical side. The vertex of an edge is the endpoint of the beams that structure the sides of the point.
Angles are supplementary angles:
Straight lines measure 180°. That implies that these two edges are beneficial. Reciprocal edges structure a correct point (L shape) and have a whole of 90 degrees. Advantageous points structure a straight line and have a whole of 180 degrees.
four sets of supplementary angles:
Two points are said to be advantageous when the aggregate of the two edges is 180°. At the point when a transversal converges with two parallel lines eight edges are created. The eight edges will together frame four sets of comparing points. Edges 1 and 5 comprises one of the sets.
supplementary angles form a linear pair of angles:
Yet, just a few arrangements of points that are advantageous are direct matches. Strengthening edges are edges that total to 180 degrees. Direct matches are edges that structure a straight line, the edge proportion of a straight line is 180 degrees, so direct combines must be advantageous.
