An $87$ degree counter$-$clockwise angle is measured from a bearing of N$42$E$.$ What

would be the new bearing?

N$45$W

What is the angle in between two bearings of $S45-{42}^{\text{'}}-{08}^{\text{'}\text{'}}W$ and $N10-{32}^{\text{'}}-{47}^{\text{'}\text{'}}W?$

$123{15}^{\text{'}}os{5}^{\text{'}\text{'}}$

Savannah is measuring the angles of a $4-$sided parcel. The first three readings are

DAB$=111{52}^{\text{'}},$ABC$=57{12}^{\text{'}}$&$BCD=67{56}^{\text{'}}$ respectively. What should the last

measurement be theoretically?

$124{00}^{\text{'}}$

If the last angle reading was measured as $122{40}^{\text{'}},$ please correct each of the

readings so that we have appropriate closure.

DAB: $111{32}^{\text{'}}$

ABC:$56{52}^{\text{'}}$

$BCD$:$67{36}^{\text{'}}$

CDA:$124{00}^{\text{'}}$
