look at the picture i have sent
Draw a picture of a building and a one mile (or 5280 feet) distance to a point from the base of the building.
The angle of elevation is given as 11° and we want the height of the building or x.
tan(11°) = x/5280
5280 tan(11°) = x
1026.3 feet = x
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Hope this helps!
Have a great day!
30 + 8d = 102
8d = 102 - 30
8d = 72
d = 72/8
d = 9....you would have to walk 9 dogs
The answer to the equation is 17
