San Francisco's two tallest buildings are SalesForce Tower at 1070 feet and the TransAmerica Building at 853 feet. Imagine you are looking out a window on the top floor of the TransAmerica Building (at a height of 695 feet) and you can see the top of Sales Force Tower. You estimate the angle of elevation from your horizontal line of sight to the tower to be about 10. About how many miles apart are the two buildings? a. First: DRAW THE DIAGRAM b. Figure out the distance in feet. Then use the fact that there are 5280 feet in a mile.
