What is the measure of? angle PQR<br> [Not drawn to scale)<br> -51<br> -55<br> -74<br> -78
soldi70 [24.7K]

<u>Given</u>:

The exterior angle P is 74°

The measure of ∠PRQ is 51°

We need to determine the measure of ∠PQR

<u>Measure of ∠QPR:</u>

From the figure, it is obvious that P is the intersection of the two lines.

The angle 74° and ∠QPR are vertically opposite angles.

Since, vertically opposite angles are always equal, then the measure of ∠QPR is 74°

Thus, the measure of ∠QPR is 74°

<u>Measure of ∠PQR:</u>

The measure of ∠PQR can be determined using the triangle sum property.

Thus, we have;

\angle PQR+\angle QPR+\angle PRQ=180^{\circ}

Substituting the values, we get;

\angle PQR+74^{\circ}+51^{\circ}=180^{\circ}

       \angle PQR+125^{\circ}=180^{\circ}

                  \angle PQR=55^{\circ}

Thus, the measure of ∠PQR is 55°

Hence, Option B is the correct answer.
