Answer:
x=15
Step-by-step explanation:
Supplementary angles are two angles that equal the sum of 180 degrees.
Take 4x and 8x and make it equal to 180
4x+8x=180
Add like terms:
12x=180
Divide:
x=15
To check:
Plug in 15 to both expressions
4(15)=60
8(15)=120
Add them up and they equal 180 degrees
Hope this helps! :)
