the field's diagonal has length 20√2
So, if the staff has height h, then
h/(20√2) = tan30°
Now just solve for h.

A flagstaff is fixed at corner of square room of the side 20 m. The angle of elevation of the top of the flagstaff form opposite corner of the room is found to be 30 degree . Find the hight of the flagstaff with figuer.
Response
Tan30°=p/b
1/root3=p/30
p=17.32m
