Answer:
its rectangle
Step-by-step explanation:
Y = x - 1
and uh uh there aren’t any extra points but cool
2cos^2x+cosx-1 = 0
2cos^2x + 2cosx - cosx - 1 = 0
(2cos^2x + 2cosx) - (cosx + 1) = 0
2cosx(cosx + 1) - 1(cosx + 1) = 0
(cosx + 1)(2cosx - 1) = 0
cosx+1 = 0 or 2cosx-1 = 0
cosx+1 = 0 gives cosx = -1, x = PI
2cosx-1 = 0 gives cosx = 1/2, x = PI/3 or x = 5PI/3
answer: x = PI/3 or x = PI or x = 5PI/3
Answer:
A(2, -1)
B(6 -1)
C(4, -4)
Not my strongest point but thats seems right
