Manyatta Village is 74 km North West of Nyangata Village. Chamwe village is 42 km west of Nyangata. find the bearing of Chamwe from Manyatta

Answer 1

starting from M, you go 74 SE and 42 W
That is
(52.33,-52.33) + (-42,0) = (10.33,-52.33)

tanθ = -52.33/10.33 = -78.8°

So, the bearing is 168.8° or E 78.8° S or S 11.2° E
