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.

Math work help wanted
Sidana [21]

Answer:

\frac{31}{20}\pi

Step-by-step explanation:

The circumference of circle G is 2pi, which means that HJ is equal to 81/360*2pi = 9pi/20, which means that RJ is equal to 18pi/20-9pi/20 = 9pi/20. Therefore, RHJ is equal to the circumference of the area minus RJ, which is equal to 40pi/20 - 9pi/20 = 31pi/20

I hope this helps

General Formulas and Concepts;

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 9(3)ˣ

x = -1

<u>Step 2: Solve</u>

  1. Substitute:                    f(-1) = 9(3)⁻¹
  2. Evaluate:                       f(-1) = 9(1/3)
  3. Multiply:                        f(-1) = 9/3
  4. Divide:                           f(-1) = 3
