Answer:
Step-by-step explanation:
Quadrilateral BCDE has coordinates B(-8,4), C(0,4), D(8,8) and E(0,8).
Quadrilateral B'C'D'E' has coordinates B'(-2,1), C'(0,1), D'(2,2) and E'(0,2).
When we analyze the coordinates carefully, we realize that the coordinates of the preimage quadrilateral is multiplied by ¼ to obtain the coordinates of the image triangle.
Therefore the rule of the dilation is
Answer:
x=-8
Step-by-step explanation:
on squaring both sides
either x-2=0 or x+8=0
either x=2 or x=-8
Putting x=2 in original equation, we get
7=7 hence, it is not an extraneous solution
Putting x=-8 in original equation
i.e. 3=-3
Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
Answer:
Step-by-step explanation:
ACB is an inscribed angle
so ∠ACB = 1/2 mAB
Hence we got
