8) Given a circle with diameter
, is it possible to
draw tangents to B and C from an external point X? If
so, make a sketch. If not, explain why it is not
possible.

Explain why P and Q are supplementary.
10) A satellite in geostationary orbit remains above the
same point on the Earth’s surface even as the Earth turns. If

11) Mount Everest is the Earth's
highest mountain. It is located in
the Mahalangur section of the
Himalayas. Its peak is 8,848
meters (29,029 ft) above sea
level and is the 5th furthest
point from the center of the
Earth. By March 2012, Everest
has been climbed 5,656 times
with 223 deaths. Most climbers
need to use bottled oxygen to
reach the summit of this
mountain.
Once at the top (or summit) of this mountain, what is the distance from the summit to the horizon to the
nearest mile? In other words, on a clear day, how far can the eye see from the summit? (the diameter of the
earth is 7,918 miles)
