Sorry.....the 'waiting for moderation...' thing is not working again today. I cannot see your diagram.
LJ = 20cos(60)
JK = 20sin(60)
Area = (1/2)*LJ*JK
note that cos(60) = 1/2 and sin(60) = sqrt(3)/2
How come you can see this but I cannot? All of the Q's, submitted for the last couple of days , with diagrams (INCLUDING answers I submitted with diagrams) STILL display 'waiting for moderation...' ????
Currently I’m using an iPad and this particular image is clear. It’s a right-angled triangle, LJK,
angle L is 60deg, hypotenuse LK is 20.
There are other images in other postings which do seem to suffer from the “waiting for moderation” with the iPad.
Well that's interesting, I can't even see my own diagram either... Thank you for the help Alan, I hope this isn't a permanent problem. Could it be because of the slow phasing out of Adobe Flash Player from Google Chrome? (I'm just spitballing here)
