Elsa really likes to travel. After visiting Seattle she travels to St. Louis to see the Gateway Arch.

When she takes pictures with the Arch she is 200 feet
away from it and knows the Arch is 630 feet tall.

At what angle does she have to look up in order to see
the top of the Gateway Arch?

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
