Answer: 16 degree
Explanation:
When two lines intersect at a point then we obtained two equal pairs of vertical angles in which one pair is of obtuse angles and another pair is of acute angles.
Here, lines p and q are intersecting at point O such that (2x+13)° and (3x-3)° is the pair of acute vertical angles,
Hence, By the above statement,
(2x+13)° = (3x-3)°
⇒ 2x + 13 = 3x - 3
⇒ 2x - 3x = -3 - 13
⇒ - x = -16
⇒ x = 16
