Use a scale drawing to determine the magnitude of the fourth displacement. A spelunker is surveying a cave. She follows a passage $$180\mathrm{m}$$ straight west, then $$230\mathrm{m}$$ in a direction $$45^{?}$$ east of south, and then $$280\mathrm{m}$$ at $$30^{?}$$ east of north After a fourth unmeasured displacement, she finds herself back where she started Express your answer in meters. Part B Determine the direction of the fourth displacement. Express your answer in degrees.
