4. While stuck in eastbound traffic on the Eisenhower (I-290), Ms. Tobin looks up and sees the
Sears Tower in the distance. Checking the mile markers on the highway, she knows that the
Sears Tower is 10 miles away. Turning slightly to the north, she sees the Goodyear Blimp,
hovering directly over Wrigley Field, which is 4.6 miles from the Sears Tower. Being stuck in
traffic and bored, she takes out a protractor and determines that the angle formed by her line of
sight to the Sears Tower and her line of sight to the Blimp is 26.4. How far is she from Wrigley
Field?
26.4
