The angles x – 10° and 190° – x are (a) interior angles on the same side of the transversal (b) making a linear pair (c) complementary (d) supplementary

Answer»

(d) supplementary

When the sum of the measures of two angles is 180o, the angles are called supplementary angles.

x – 10o + 190o – x = 180o

190o – 10 = 180o

180o = 180o

LHS = RHS
