Answer to Problem 23HP

Yes, the statement passed by Rodrigo is correct.

Explanation of Solution

According to Terence:

When you look you will get an angle of elevation is $35°$ and when you look down the angle of the depression is $55°$ . It is nothing but a complement of $35°$ .

According to Rodrigo:

When you look down the angle of the depression is same as angle of elevation that means $35°$

Know that:

Horizontal lines are parallel. Alternate Interior Angles Theorem shows that the angle of depression and the angle of elevation are congruent. Thus, if the angle of elevation is of $35°$ then the angle of depression is of $35°$ :

The below figure is represented the given statements of Terence and Rodrigo:

  

Therefore, the statement given by Rodrigo is correct.
