The Apache are only one of many tribes that inhabited North America when
the Europeans arrived. Others included the Sioux, the Cherokee, Shawnee,
Pawnee, Mohawk, Seneca, Cheyenne, Owasso, Oglala, Cayuga, Onandoga,
Iroquois, and many more.
Never seen that question before I would say the correct adverb would be sank
x(angle1)+(3x-5)(angle 2)=143(sum of both angles).
x+3x-5=143
combine like terms: 4x-5=143
add 5 to both sides: 4x=148
divide both sides by 4: x=37
substitute for x: angle 1=37, angle 2= 106
I can’t answer if you do not show the excerpt please
