the angles of of evolution of the top of a hill from the City centres of two towns on either side of the hill are observed to be 30Â° and 60Â° respectively. if the distance of hill of the top from the city centre of first is 9 kilometre find in kilometres the distance uphill of the top from the other City Centre to the two places of decimal. ( use root 3 is equals to 1.73)

Question

the angles of of evolution of the top of a hill from the  City centres of two towns on either side of the hill are observed to be 30Â° and 60Â° respectively. if the distance of hill of the top from the city centre of first is 9 kilometre find in kilometres the distance uphill  of the top from the other City Centre to the two places of decimal. ( use root 3 is equals to 1.73)

That's elevation, not evolution! Consider the fact that the sides of a 30-60-90 triangle are in the ratios 1:√3:2 and just scale that up for your diagram.
