suppose that Angle Hik and Angle LIJ are verticle angles. find their measures if the following conditions apply. see picture

10. m∠HIK (2x+15)°, m∠LIJ = (5x-27)°, m∠HIK =
if they are vertice angles then they are equal to each other or
they both add up to 180°
A.
2x+15=5x-27
3x=42
x=14
B.
(2x+15)° + (5x-27)° = 7x-12
7x-12 = 180
7x=192
x = 27 3/7 or 27.43
