Need Help!!! 2H 16a & b
Three tourists T1, T2 and T3 at ground level are observing a landmark L. T1 is due north of L, T3 is due east of L, and T2 is on the line of sight from T1 and T3 and between them. The angles of elevation to the top of L from T1, T2 and T3 are 25', 32' and 36' respectively.
a) show tan angle LT1T2 = cot 36 / cot 25
b) use the sine rule in triangle LT1T2 to find, correct to the nearest minute, the bearing of T2 from L
Please show all working
