<h3>Answer: Third choice, 160 degrees</h3>

=======================================================

Explanation:

See the attached image below to see one way you could draw the diagram based on the given info. The drawing is not to scale.

The color coded angles hopefully let you see which angles are congruent to one another

  • Angle EXB = Angle DXE (in red)
  • Angle CXD = Angle DXB (in blue)
  • Angle AXC = Angle CXB (in green)

These three pairs of congruences are possible because of the angle bisections that occur.

Since EXB is 20, this means DXE is 20 as well. They combine to 20+20 = 40, which is the measure of angle DXB (angle addition postulate).

Angle DXB is congruent to CXD, so both are 40 and they combine to 40+40 = 80. This is the measure of angle CXB.

Finally, angle CXB = 80 doubles to 160 which is the measure of angle AXB. Or you could say

angle AXB = (angle AXC) + (angle CXB) = 80 + 80 = 160.

80 degrees because it decreases by a half each time so by the time it is E (the fourth letter) it has gotten to 20 so the answer is 160

Use the elimination method by subtraction to solve for x and then y.
diamong [38]

Answer:

Step-by-step explanation:

Both equations have -7y. You can eliminate them by subtracting one equation from the other:

Multiply equation 1 by -1, then add it to equation 2:

-2x + 7y = 74

3x - 7y = -83

———————

x = -9

2x - 7y = -74

2(-9) - 7y = -74

-7y = -56

Y = 8

(x,y) = (-9, 8)

Do the following side lengths form a triangle?<br><br> 6, 18, 14
kogti [31]

Answer:

  yes

Step-by-step explanation:

The triangle inequality requires the sum of the two short sides exceed the long side.

  6 +14 = 20 > 18

The triangle inequality is satisfied by these numbers, so they could be the side lengths of a triangle.

Artemon [7]

Answer:

Step-by-step explanation:

\left(3+\frac{\frac{9}{2}}{\sqrt{5}}\right)\left(2-\sqrt{5}\right)n+\left(3-\frac{\frac{9}{2}}{\sqrt{5}}\right)\left(2+\sqrt{5}\right)

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{b}{c}}{a}=\frac{b}{c\:\times \:a}

=\left(\frac{9}{2\sqrt{5}}+3\right)\left(2-\sqrt{5}\right)n+\left(-\frac{\frac{9}{2}}{\sqrt{5}}+3\right)\left(2+\sqrt{5}\right)

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{b}{c}}{a}=\frac{b}{c\:\times \:a}

=\left(\frac{9}{2\sqrt{5}}+3\right)\left(2-\sqrt{5}\right)n+\left(-\frac{9}{2\sqrt{5}}+3\right)\left(2+\sqrt{5}\right)

=\frac{-12-9\sqrt{5}}{2\sqrt{5}}n+6n+\left(3-\frac{9}{2\sqrt{5}}\right)\left(2+\sqrt{5}\right)

=\frac{-12-9\sqrt{5}}{2\sqrt{5}}n+6n+\frac{12-9\sqrt{5}}{2\sqrt{5}}+6

=\frac{\sqrt{5}\left(\left(3\sqrt{5}-12\right)n+12-9\sqrt{5}\right)}{10}+6

If a randomly selected orphan pet in an animal shelter of Salt Lake City is a dog, what is the probability that it is a Chihuahu
Likurg_2 [28]

We also need the first half of the question ... the part you didn't copy ... the part
that lists the different species of animals in the shelter and how many there are
of each. 

I realize that several times, a problem will include information that's not needed in
order to solve it, but this is not one of those times.  We need all of the information
that's there, with the possible exception of the name of the city where the shelter
is located.
