How do I find the area of JKL?

Thanks again!

LJ = 20cos(60)

JK = 20sin(60)

 

Area = (1/2)*LJ*JK

 

note that cos(60) = 1/2 and sin(60) = sqrt(3)/2

Sorry.....the  'waiting for moderation...'   thing is not working again today.   I cannot see your diagram.

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.

Strangely, I can see the images from the Answers page, but if I jump into the answer itself I can’t!!

(Except for the right angled triangle, which I can see from within the question and answers).

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)
