Work backwards with pythagoras' theorem:
c^2=a^2+b^2
Here, a and b both equal to x. Therefore, you can write this as 8^2=2x^2. So 64=2x^2. Sqrt on both sides to give you 8=2x, hence x=4. However I must warn you that this working out may have a flaw, as I found that x actually equals to 5.66
Answer:
D) the lines coincide
Step-by-step explanation:
1. y = 4 - x
2. 2y = 8 - 2x
divide eq2 by 2:
y = 4 - x
eq 1 and 2 are identical
