Answer #1

From the figure, sin 0= X=B sin e X= 15 msin 30º=7.5m this is x component of vector B, similarly, for y component of vector BB=7.5mî+12.99mì A-BB-8.0mj-7.5mi-12.99mj À-B=-7.5m î–20.99 m Î now, lets apply the phythagoras theorem for its magnitude, JÄ-From the figure, a=tan 20:59 a=tan-(2.798) A-B a = 70.34 degree with negative x axis, now, angle with positive x axis, 180°Thus, magnitude of B-A=20.29 m Ans.
