Vu, a bystander at the Pegasus Parade, is lying
on his back and observing a large balloon of a
cartoon character, floating directly above
Calhoun Street. Vu is located 30 feet from a
point on the street directly beneath the balloon.
To see the top of the balloon, he looks up at an
angle of 58° To see the bottom of the balloon,
he looks up at an angle of 470
To the nearest tenth, what is the distance, in
feet, from the top of the balloon to the street?
How tall, in feet, is the balloon?
