Answer:

Janelle's conclusion is correct, because the value of x is 15

Step-by-step explanation:

step 1

Find the value of x

we know that

m∠MKJ=m∠LKM+m∠LKJ

substitute the given values and solve for x

80°=(2x+10)°+(3x-5)°

80=5x+5

5x=80-5

5x=75

x=15

step 2

Find the value of x assuming that KL bisect the angle MKJ

so

m∠LKM=m∠LKJ

(2x+10)°=(3x-5)°

3x-2x=10+5

x=15

therefore

Janelle's conclusion is correct, because the value of x is 15

Answer:

Option c

Step-by-step explanation:

Measure of angle MKJ = 80°

Since KL is the bisector of ∠MKJ

Therefore, [m∠(MKJ) = m∠(MKL) + m∠(LKJ)]

80° = m∠(MKL) + m∠(LKJ)

∠MKL = (2x+10)° and ∠(LKJ) = (3x-5)°     [given in the figure]

Therefore, (2x-10) + (3x-5) = 80

                 5x + 5 = 80

                 5x = 80 - 5

                 5x = 75

                 x = \frac{75}{5}

                 x = 15

That means for x = 15 line segment KL is the bisector of ∠MKJ.

Option C will be the answer.

Find the surface area of a square pyramid with a length of 5 cm and a slant height of 8cm.
Tems11 [23]
Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area  of while pyramid = 4 * 20 + 25 = 105 cm^2

Volume of the cone = (1/3) pi r^2 h
  = (1/3) pi * 5^2 * 8
  =  209.44  ft^2

indicate the equation of the line, in standard form, that is the perpendicular bisector of the segment with endpoints (-1,6) and
vladimir1956 [14]

The equation of the line, in standard form, that is the perpendicular bisector of the segment with endpoints (-1,6) and (5, 5) is <u>12x - 2y = 13</u>.

In the question, we are asked to indicate the equation of the line, in standard form, that is the perpendicular bisector of the segment with endpoints (-1,6) and (5, 5).

The slope of the line with endpoints (-1,6) and (5,5), can be calculated as:

m = (6 - 5)/(-1 - 5) = 1/(-6) = -1/6.

Thus, the slope of the perpendicular bisector = -1/m = -1/(-1/6) = 6.

The perpendicular bisector passes through the midpoint of the line with endpoints (-1,6) and (5,5), which can be calculated as:

(x₁, y₁) = ( {(-1 + 5)/2},{(6 + 5)/2} ),

or, (x₁,y₁) = (2, 11/2).

Thus, the required equation can be shown as:

(y - 11/2) = 6(x - 2), which can be shown in the standard form as follows:

(2y - 11)/2 = 6x - 12,

or, 2y - 11 = 12x - 24,

or, 12x - 2y = 13.

Thus, the equation of the line, in standard form, that is the perpendicular bisector of the segment with endpoints (-1,6) and (5, 5) is <u>12x - 2y = 13</u>.
