Question: Hi, I am having a bit of trouble with the following question:
Karen is standing 23 metres away from the base of a 23 metre high house. Assume that Karen's eyes are 1.5 metres above ground. Find the elevation of the top of the house from Karen's eye line.
 

 

Hi Chloe,

I drew a diagram.

K is Karen's eye, 1.5 m above the ground and t is the angle of elevation. From the diagram

tan(t) = 21.5/23

Find t.
