G+_Jason Perry Posted May 17, 2017 Author Share Posted May 17, 2017 How good are you with circles. I want to find out the height of a gothic arch with a base of 12 units. I am on khan academy right now watching some videos. Link to comment Share on other sites More sharing options...
G+_Damien Wessling Posted May 17, 2017 Share Posted May 17, 2017 Which variant of Gothic Arch? Link to comment Share on other sites More sharing options...
G+_Jason Perry Posted May 17, 2017 Author Share Posted May 17, 2017 I am looking for the length of AE, so I can figure out angle AEB The radius of the circle (DB) is 18 The length of AB is 6 Is it bad that I am enjoying learning how to find as many values to do with this arch.

G+_Jason Perry Posted May 17, 2017 Author Share Posted May 17, 2017 Think I just figured it out If I flip the image I have created a chord where I know the radius and the distance of the chord from the centre Chord length = 2 * sqrt(r^2-d^2) Link to comment Share on other sites More sharing options...

G+_Jason Perry Posted May 17, 2017 Author Share Posted May 17, 2017 I hate hindsight, I look back and noticed I have a right angle triangle and know the length of two of the sides. Link to comment Share on other sites More sharing options...
