Thread: One spot and distance known, Second spot unknown

Hi there, I know the coordinates of points E and Q, so I know their euclidean distance L.
I'm looking for the point W with coordinates (a,b) related to other known values?

Draw a line through Q parallel to the y-axis and add further to the diagram so that you have 2 right angled triangles. Then use trigonometry to get the other 2 sides in each triangle.

Hello,cesar2012!

I know the coordinates of points E and Q, so I know their euclidean distance L.
I'm looking for the point W with coordinates (a,b) related to other known values.
