No, could you please tell me how to, I actually have no idea... I tried uploading an image however, it doesn't work.

I actually can't really see that, it's pretty blurry.

Really, it looks good on mine, maybe your screen is smaller???

Anyway, the angle of elevation is from the horizontal looking up.  :)

And and angle of depression is from the horizontal looking down.

d for down

d for depression.

tan 12 = x/5

5* tan 12 =x

x = 1.06 miles

Do you agree? @Melody

Yes, once again that is excellent.  You have laid it out nicely too :)

except.... if you had to answer properly you have to write in words,

There is no x in the question. It is the vertical change in height that you have found.
