I have absolutely no clue what ur saying lmao TT
Write Josie on a piece of paper. Then to the left of Josie, write Peter, the line between them is 6 km.
Above Peter write Lucia. The line between Peter and Lucia is 3 km. To the right of Lucia write Craig. The line between Lucia and Craig is 2 km. If you unite Craig with Josie, it gives you a right trapezoid.
I think it asks you the distance between Craig and Josie, right? In this case, draw a line from Craig, down to the line between Peter and Josie. It makes a right triangle. Right triangles have the formula c ^ 2 = a ^ 2 + b ^ 2, where a, b are the right angle lines (the lines that form the right angle) and c is the other line.
You need to find c which is the distance between Craig and Josie, using the formula. Aka you need to write, c ^ 2 = 3 ^2 + 4 ^ 2 => c^ 2 = 25 => c ^ 2 = 5 => The Distance between Craig and Josie is 5 km.
(This is because we know that Lucia - Craig distance is 2 km and if you draw the line that makes a triangle, you separate the base of the trapezoid in two parts. One part is equal to the distance between Lucia and Craig and the other one you can find out by doing the math. Distance between Peter and Josie - (minus) distance between Lucia and Craig. Which is 6 -2 = 4 km.)
Hope this helps!
