Last year I felt an earthquake while I was watching television. The earthquake
that I experienced
produced a wave that travelled through the earth at a speed of 1.3 X 10^4
m/s. This wave is incident on a
boundary between two types of materials. If this incident angle is 35
and the refracted
the second medium is 32 what is
the speed of the wave in the second medium

Did you measure all of that when you felt it or after the fact?
The speed in the 2nd medium is n1/n2 = sin(32°) / sin(35°) = 0.924 times the speed in the 1st medium.
Assuming standard definition of incident and refracted angle and that you meant degrees and not in fact radians.
is like this it
really hard to
read so format your
