Correct answer is: 156

Explanation:

Let the angles be 3x, 5x, 9x, 13x

3x + 5x + 9x + 12x = 360.

 30x = 360

x = 120

 Angles are 36, 60, 108, 156.

largest angle is 156

raju ? Jan 8 '2020 at 7:49

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.
