solve the following problem with the correct answer please, please make sure to show all work so I can understand.

Elevation of top Q of a hill, a staff of 2 m height was erected and observations were made from stations P and R, 60 m apart. The horizontal angle measured at P between R and the top of the flag staff was 60°30' and that measured at R between the top of the flag staff and P was 68 18'. The angle ofelevation to the top of the flag staff from P = 10°12' and from R = 10°48'. Staff readings on BM when instrument was at P = 1.965 m and that with instrument at R = 2.055 m. Calculate the elevation of the top of the hill if reduced level of BM=100m?
