What is the measure of KPN?<br> A. 35°<br> B. 50°<br> C. 60°<br> D.65°<br> E. 70°
luda_lava [24]

Answer:

Option (B)

Step-by-step explanation:

From the picture attached,

NL and KM are the two lines intersecting at a point P.

Therefore, ∠KPN ≅ LPM [Vertical angles]

In ΔPLM,

m∠LPM + m∠PML + m∠PLM = 180° [Property of a triangle]

m∠LPM + 70° + 60° = 180°

m∠LPM + 130° = 180°

m∠LPM = 180° - 130°

m∠LPM = 50°

Therefore, m∠KPN = 50° [vertical angles]

Option (B) will be the correct option.

Find the area of the blue sector of the circle. Round to the nearest hundredth.
Varvara68 [4.7K]
A diagram must be associated with the question above. Based on what I researched, this is what I got.

The blue sector of the circle is 120 degrees.

area of the blue sector = 1/3  of pi * 2^2
                                     = 4.19cm2

I hope this answer helps.

<u>Algebra I</u>

  • Coordinates (x, y)
  • Terms/Coefficients
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

2x + y = 5

3x - 2y = 4

<u>Step 2: Rewrite Systems</u>

<em>Manipulate 1st equation</em>

  1. [Subtraction Property of Equality] Subtract 2x on both sides:                      y = 5 - 2x

<u>Step 3: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em> [2nd Equation]:                                                                         3x - 2(5 - 2x) = 4
  2. [Distributive Property] Distribute -2:                                                                3x - 10 + 4x = 4
  3. [Addition] Combine like terms:                                                                        7x - 10 = 4
  4. [Addition Property of Equality] Add 10 on both sides:                                   7x = 14
  5. [Division Property of Equality] Divide 7 on both sides:                                 x = 2

<u>Step 4: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em> [Modified 1st Equation]:                                                           y = 5 - 2(2)
  2. Multiply:                                                                                                             y = 5 - 4
  3. Subtract:                                                                                                            y = 1
