 Solve the problem using trigonometric ratios and round your answer to the nearest whole number.

Michael,
You and I worked this out the exact same way... however, my calculator repeatedly give me
32/cos(65) = 75.72 ft ... Not sure why you are getting 83 ft

I accidentally put     35 / cos(65)   rather than   32 / cos(65)     on my calculator.  But I changed it.

Ah.  I see.  I was trying to figure out where I had made an error since I have looked at quite a few of your answers and am aware of your expertise.  Have a great day.
