Answer:
4x + 8x = 180
12x = 180
divide by 12 on both sides:
X = 15
4 x 15 = 60 degrees
8 x 15 = 120 degrees
Hello! answer: x = 15
Step-by-step explanation:
Since this is a supplementary angle it will equal a total of 180 15 × 4 = 60 15 × 8 = 120 you add these up and... 60 + 120 = 180 therefore x = 15 and
4x = 60 and 8x = 120 HOPE THAT HELPS!
