Solve for x and fill in your answer in the blank given

AB = 2 cm; BC = 4 cm

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

you can use a^2+ b^2=c^2
