Find the measure in degrees of angle MKL. M N 155° ? КК 75° U L

Answer:

mMKL = 115°

Step-by-step explanation:

Using the property of intersecting chords in a circle, we have that one angle in the intersecting point is the average of the arcs intercepted by the angle and its vertical angle.

So, to find the measure of the angle MKL, we have:

mMKL = (1/2) * (mML + mNU)

mMKL = (1/2) * (155 + 75)

mMKL = (1/2) * (230)

mMKL = 115°

A regular pentagon shares a common center with a regular hexagon. If LM¯¯¯¯¯ || AB¯¯¯¯¯, across how many lines of reflection can
Thepotemich [5.8K]

This problem is very difficult to imagine without the figure. However I dug up on other sources and I think I found the correct figure to work with (see the attached pic).

 

We can see that in the figure, the hexagon is inscribing the pentagon. What is meant here to be lines of reflection simply means lines of symmetry. If we take on the hexagon alone, there are a lot of lines of symmetry. We can create the line intersecting E & B and the figure would still be symmetrical on both sides or D & A, F & C and etc. So there are a lot for hexagon alone.

 

However in this case, our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.

 

Therefore the line of reflection is only <u>1.</u>

If you do this ill give you a bunch of points please!!!!!!!
Zarrin [17]

a)

(59, 76) and (65, 100)

y - y1 = m(x - x1)

y - 100 = (100-76)/(65 - 59)(x - 65)

y - 100 = (24/6)(x - 65)

y - 100 = 4(x - 65)

y - 100 = 4x - 260

y = 4x - 160

b)

x = 90

y = 4x - 160

y = 4(90) - 160

y = 360 - 160

y = 200

200 chirps per minute

c)

y = 120

y = 4x - 160

120 = 4x - 160

280 = 4x

x = 70

70 degrees

the volume of a rectangular pyramid is 192 cubic units. if it's dimensions are reduced to one-fourth their original lemgth. what
vekshin1
We know that
scale factor=1/4
so
volume of the smaller pyramid=[scale factor]³*volume original pyramid
volume original pyramid=192 unit³
volume of the smaller pyramid=[1/4]³*192---> (1/64)*192----> 3 units ³

the answer is

3 units³
