Step-by-step explanation:
Add (4x - 1)⁰ and (3x - 8)⁰ and equate to 180⁰.
4x - 1 + 3x - 8 = 180
7x - 9 = 180
7x = 189
x = 27
Answer:
x=27
Step-by-step explanation:
theyr supplementary angles so add them and set them equal to 180:
4x - 1 + 3x - 8 = 180
combine like terms:
7x -9 = 180
isolate x by adding 9 on both sides:
7x = 189
divide by 7 on both sides:
x=27
