# Can someone solve this?

I just need to make sure that I did this right (my work is on the right of the page but you can still see my messy triangle lol please ignore that) so can someone show me the steps and the answer? Thanks!

Using soh cah toa, you'll have opposite leg / adjacent leg so use tangent.

The complete height of building plus mast , x, you get by tan 50 = x/40,

or 40 tan 50 = x

The height of just the building , y, you get by tan 39 = y/40

or 40 tan 39 = y

so then do x - y
