just set it up. If D is x from the base of the mountain of height h, then
h/x = tan 51°43'
h/(x+350) = tan 42°36'
solving for x, we get
h/tan51°43' = h/tan42°36' - 350
Now just solve for h.
I get h=1173
h/x = tan 51°43'
h/(x+350) = tan 42°36'
solving for x, we get
h/tan51°43' = h/tan42°36' - 350
Now just solve for h.
I get h=1173
