Reflect ΔECD over segment AC. This establishes that . Then, translate point E' to point A. This establishes that . Therefore, ΔACB ~ ΔECD by the AA similarity postulate.
a. ∠ABC ≅ ∠E'D'C'; ∠E'D'C' ≅ ∠ABC
b. ∠ACB ≅ ∠E'C'D'; ∠D'E'C' ≅ ∠BAC
c. ∠ACB ≅ ∠E'C'D'; ∠E'D'C' ≅ ∠ABC
d. ∠ABC ≅ ∠E'D'C'; ∠D'E'C' ≅ ∠BAC

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

on your paper it doesn't say the answer but the the answer is altitude
