Can somebody help me with this?
which part are you needing help with?? the lengths or the slopes or both?
For the slope part, you know how to find it! Just figure out the other three like how you did the first one! :) For the Length part, you have to use Pythagoras theorem. Has your teacher taught you this. For the length of AB, side A is 4 and side B is 3. Now we just have to figure out side C. So set up the equation like this, 4^2 + 3^2 = C^2. ---> Solve for C.16 + 9 = C^225 - C^2 --> square root both sides5 = C Side AB = 5 Do the same way above to solve for side CD. Hope this helps! Good Luck! :)
