**Henry**, Tuesday, August 10, 2010 at 12:26pmThe line of sight of the 2nd observer

is represented by the hypotenuse of a rt triangle, and the height of the

meteor is represented by the ver. side

of the rt triangle.The acute angle bet.

ween the ver. side and hyp. = 50 deg.

The angle of elevation is equal to the

other acute angle or 40 deg.

Tan(40) = h/30,

h =30*Tan(40) = 25.2 =height of

meteor

Tan(70) = 25.2 / d,

d = 25.2/Tan(70) = 9.2 = distance of

meteor.

**Henry**, Tuesday, August 10, 2010 at 12:36pmCORRECTION!!

Sin(70) = 25.2/d,

d = 25.2/Sin(70) =26.8.
