- trig pls.. help me -
**Reiny**, Monday, May 2, 2011 at 4:15pmmake a sketch, on a straight line mark off points

X, Y, and Z, where Z is then end of the altitude SZ, where S is the satellite.

Angle X = 40°

angle SYZ=70°

XY = 24

in triangle XYS,

angle x=40, angle XYS = 110 , and angle XSY = 30°

by the sine law:

YS/sin40 = 24/sin30

YS = 30.8538

in right-angled triangle SYZ,

RZ/30.8538 = cos 70

RZ = 10.55

the height is appr. 10.6 km
