At the foot of a mountain the elevation of its summit is 45 degrees. After ascending one
KM towards the mountain upon an incline of 30 degrees, the elevation changes to 60
degrees. Find the Height of the mountain?  Choices: A) 1.333Km B) 1.366Km C) 1.233Km D) 1.266Km E) None of these
At the foot of a mountain the elevation of its summit is 45 degrees. After ascending one KM towards the mountain upon an incline of 30 degrees, the elevation changes to 60 degrees. The Height of the mountain is guven by   [ Height -- sin 30 ] = [ Height -- cos 30 ] tan 60   whence Height = [tan 60 cos 30 -- sin 30 ] / [ tan 60 -- 1 ] km = 1.366 km   ANSWER:1.366Km
