Hey all. I hope I am in the right section. Easy Question... Well maybe for you - Not for me!! Black line is 20ft. Green Line is 6ft. How many feet is the red line?
I supposed it is a right-angled triangle because of the way it is drawn. Red line is the longest so the black line + green line will be equal to the red line. Using Pythagoras theoreom -
Black Line (20)^2 + Green Line (6)^2 = Red Line^2 and just calculate it to get red line. Sorry if it's confusing.
