**Reiny**, Monday, October 8, 2012 at 9:12amMake the following diagram

Draw a base line , label the balloon as B and above the base line

Label the point directly below the balloon A on the base line

label the two stations as C and D so that

angle ACB = 78.2 and angle ADB = 17.6

Now in triangle BCD , CD = 10 ,

angle BCD = 101.8 , (exterior angle theorem)

and angle CBD = 60.6° (angle sum of triangle theorem)

Using the sine law BC/sin17.6 = 10/sin60.6

you can find BC, which is then the hypotenuse of

triangle ABC

then use

sin 78.2 = height/BC to find the height
