Answer:

  A. CCW 180° about the origin

Step-by-step explanation:

Figure B appears to be a reflection of Figure A across the origin. Such a reflection can be described by any of ...

  • reflection across the origin
  • rotation 180° CW about the origin
  • rotation 180° CCW about the origin
  • reflection across the x-axis followed by reflection across the y-axis
  • reflection across the y-axis followed by reflection across the x-axis.

6. m A = 8x - 2, m B = 2x - 8, and m2 C = 94 - 4x. List the sides of A ABC in order from shortest to
Oduvanchick [21]

Given:

In triangle ABC, m∠A=(8x-2)°, m∠B=(2x-8)° and m∠C=(94-4x)°.

To find:

The sides of the triangle ABC in order from shortest to  longest.

Solution:

In triangle ABC,

m\angle A+m\angle B+m\angle C=180^\circ              (Angle sum property)

(8x-2)^\circ+(2x-8)^\circ+(94-4x)^\circ=180^\circ

(6x+84)^\circ=180^\circ

6x+84=180

6x=180-84

6x=96

Divide both sides by 6.

x=\dfrac{96}{6}

x=16

Now,

m\angle A=(8(16)-2)^\circ

m\angle A=(128-2)^\circ

m\angle A=126^\circ

Similarly,

m\angle B=(2(16)-8)^\circ

m\angle B=(32-8)^\circ

m\angle B=24^\circ

And,

m\angle C=(94-4(16))^\circ

m\angle C=(94-64)^\circ

m\angle C=30^\circ

In a triangle the smaller angle has shorter opposite side and larger angle has longer opposite side.

24^\circ

m\angle B

AC

List the sides of triangle ABC in order from shortest to  longest is AC:AB:BC.

Therefore, the correct option is A.

Answer:

So -63 isn't the right answer. It is either 6.5 or 13/2 based on how your teacher wants the answer.

Step-by-step explanation:

I did the work to show you how i got there. It is definitely not -63. I hope this helps!
