Question

The bearing of line xy is 195 and that of line zy is 255 45'. The included angle xyz is

Answer 1

Answer:60°45'

Step-by-step explanation:

195-180=S15°W,90-15=N75°E

255°45'-180=S75°45'W

Excluded angle is 75+90+75°45'=240°45'

Then included angle is 240°45'-180°=60°45'

(OR)

BB of line XY=195-180=15

BB of line ZY=360-255.45=104.15

15+104.15=119.15

180-119.15=60°45' Included angle
