point A and B are 100m apart and are of the same as the foot of a building. the angle of elevation of the top of the building from point A an B are 21 degrees and 32 degree respectively. how far is A from the building

Answer 1

done
look at your post which you had 6 minutes before this one

Answer 2

tan 21=h/(100+x)
h=tan21(100+x)

tan 32=h/x
h=xtan32

equate 1 and 2
(100+x)tna21=xtan32
x=159.286 m

d = 100 + 159.286
d=259.286 m
