Correct answer is :90°
Explanatopn:
(i) If two angles are complementary, then the sum of their measures is 9090.
(ii) If two angles are supplementary, then the sum of their measures is 180180.
(iii) Two angles forming a linear pair are supplemetary.
(iv) If two adjacent angles are supplementary, they form a linear pair.
(v) If two lines intersect at a point, then the vertically opposite angles are always equalequal.
(vi) If two lines intersect at a point, and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles are obtuseobtuse.
