Question

horizontal distance between two trees of different height is 60m angle of depression of the first tree was seen from top of the second tree is 45 degree if height of second trees 80m
find height of the first​

Answer 1

Answer:

height of first tree=140m

Step-by-step explanation:

AB=height of second tree=80m,

angle EAD=45°;

EC=height of first tree=?

AB=CD=80m,

BC=AD=Distance between two trees=60m

then,

EC= ED+CD

or, EC=(AD× tan45°)+CD

or, EC=(60×1)+80

or, EC=140m
