**Steve**, Wednesday, November 2, 2011 at 12:23pmSet up your diagram. If x is the distance of R from the cliff, and h is the cliff height,

S: h/(x+132.6) = tan 32°36' = 0.6395

R: h/x = tan 63°13' = 1.9811

Since h is the same in both equations,

.6395(x+132.6) = 1.9811x

.6395x + 84.7977 = 1.9811x

x = 63.2064

So, h = 63.2064 * 1.9811 = 125.2119
