Part $3.$ Compute the "angles to the right", between line $AB$ and $BC($ ABC $).$

Bearing of Line $AB$:$N25{58}^{\text{'}}W$

Azimuth of Line BC: $140{52}^{\text{'}}{30}^{\text{'}\text{'}}$

Part $4.$ Compute the azimuth of line $CD($relative to north$)$ Bearing $AB=N51{18}^{\text{'}}W$; All following

angles are measured to the right ABC$=338{37}^{\text{'}}{56}^{\text{'}\text{'}},BCD=99{17}^{\text{'}}{40}^{\text{'}\text{'}}$
