Supplementary angles are two angles with a sum of 180°.
If angle F and angle H are supplementary angles then:
F + H = 180°
F = 77°
H = ( 5 x + 18 )°
so
F + H = 180°
77° + ( 5 x + 18 )° = 180°
Answer B.
If angle F and angle H are supplementary angles then:
F + H = 180°
F = 77°
H = ( 5 x + 18 )°
so
F + H = 180°
77° + ( 5 x + 18 )° = 180°
