we know that
The angle below horizontal that an observer must look to see an object is called <u>the angle of depression </u>
The angle above horizontal that an observer must look to see an object is called <u>the angle of elevation</u>
In this problem we have
the horizontal is the line KL
and the angle below horizontal between Carlos and the car is equal to
Angle LKI
therefore
<u>the answer is</u>
The angle of depression from Carlos to the car is the angle LKI
