6. Which statement is true? 8.8D

Mathematics

1 answer:

Answer:

Step-by-step explanation:

The two angles are better known as corresponding angles, and since the two lines are parallel, then the angles must be congruent. This means x = 115 degrees.

C. The values of x is 115 because the two angles shown are congruent.

<u>Why the other answers are wrong:</u>

A & B are wrong because it states the two angles are supplementary, but supplementary angles have to add up to 180 degrees and 115+115 is 230 not 180.

D is wrong because there's no logical explanation to why you would subtract 90 degrees from 115 to solve for x.

Solve x = 0.6x + 384

Gelneren [198K]

X = 0.6x + 384 |subtract 0.6x from both sides

0.4x = 384 |divide both sides by 0.4

x = 960

Which representation of a transformation on a coordinate grid does not preserve congruence?

Alex17521 [72]

Answer:

Step-by-step explanation:

Consider all options:

A. Transformation with the rule

$(x,y)\rightarrow (x,-y)$

is a reflection across the x-axis.

Reflection across the x-axis preserves the congruence.

B. Transformation with the rule

$(x,y)\rightarrow \left(\dfrac{7}{8}x,\dfrac{7}{8}y\right)$

is a dilation with a scale factor of $\frac{7}{8}$ over the origin.

Dilation does not preserve the congruence as you get smaller figure.

C. Transformation with the rule

$(x,y)\rightarrow (x+6,y-4)$

is a translation 6 units to the right and 4 units down.

Translation 6 units to the right and 4 units down preserves the congruence.

D. Transformation with the rule

$(x,y)\rightarrow (y,-x)$

is a clockwise rotation by $90^{\circ}$ angle over the origin.

Clockwise rotation by $90^{\circ}$ angle over the origin preserves the congruence.

Angle a and angle b are vertical angles with measue of angle a=x and measure of angle b=5x-80

Gelneren [198K]

Answer:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent to one another

in this problem

∠A and ∠B are vertical angles

∠A=∠B

we have

∠A=

∠B=

equate angle A and angle B

solve for x

therefore

the answer is

the measure of angle A is
