The four corners of a square are 90 degrees.
They are evenly split by the diagonal lines, so each corner is now two 45 degree angles.
The lines form triangles, which have 3 angles that need to equal 180 degrees.
Two of the angles are 45, so 45 + 45 = 90 degrees.
X = 180 -90 = 90 degrees.
Answer:
answer would be b) y = -7x -9
Step-by-step explanation:
Answer is x= 3 or x= -2
x(x+2) -3 (x+2) = 0
(x+2) (x-3) =0
x+2=0
x-3=0
so..
x=-2
x=3
hope this helped a bit good luck :)
The correct answer is b I believe
