1. ## Right-Angled Triangles...

Hi,
I have posted here because I need some assistance with a trigonometry problem. I have found out that the answer is 11.2 to one decimal place but I can not work out how to do it.

Thank you.

Thank you.
tan18 = BD/28
So BD = 28*tan(18)
tan36 = BC/28
So BC = 28tan(36)
x = BC - BD = ...?

I did not realize it was so simple...
