Is this an example of a real life situation including an angle of elevation or depression? A real life scenario is if you wanted to figure out how fare a bird is away from you. The bird is flying above a train that is 300ft away from you. Above you is a plane that is parallel to the bird, it is 500 ft above you.

Also if it is, how would you solve it?

it’s the first one your welcome

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
