Math problem....

[Smirre]

Can this problem be solved???

Check out the image attached to this message.

The problem is to calculate the lenght of X in the image. The other values in the image is the lenght of each line (line color = value color). No other values are known, no angels, only these values.

Assuming that the line with a length of 1 intersect line x at a right angle as it appears in your diagram the problem can be solved

left(x) - the part of x to the left of the line with a lenght of 1
right(x) - the part of x to the right of the line with a length of 1

X = left(x) + right(x)

7^2 = 1^2 + left(x)^2
solve for left(X)

left(X) = sqrt(48)

similarily

right(x) = sqrt(24)

x = 11.827 roughly

I don't think you can assume it is a right angle, that would be too easy.

Do they tell you anything about the black lines?

does that form a rectangle?
