Angle ABC is rotated 90 degrees counterclockwise about the origin to form angle A’B’C’. Which statement shows the measure of ang

le A’B’C’?
m∠A’B’C’ = 90 degrees


m∠A’B’C’ = 180 degrees


m∠A’B’C’ = m∠ABC


m∠A’B’C’ = 2 × m∠ABC

Answer:

m∠A’B’C’ = m∠ABC

Step-by-step explanation:

Given : Angle ABC is rotated 90 degrees counterclockwise about the origin to form angle A’B’C’.  

To Find: Which statement shows the measure of angle A’B’C’?

Solution:

We are given that Angle ABC is rotated 90 degrees counterclockwise about the origin to form angle A’B’C’.  

Rotation takes place here.

Rotation does not changes the measure of angle  

So, the measure of angle will remain same  

m∠A’B’C’ = m∠ABC

So, Option C is true .

Hence The statement shows the measure of angle A’B’C is m∠A’B’C’ = m∠ABC

On the graph of the equation X-4Y= -16 what is the value of the Y-intercept?
Nonamiya [84]

we can always find the x-intercept by simply settting y = 0, and solving for "x".

and we can always find the y-intercept by simply setting x = 0 and solving for "y".


\bf x-4y=-16\implies \stackrel{x=0}{0-4y=-16}\implies y=\cfrac{-16}{-4}\implies y=4

The vertices of a parallelogram are A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4). Which of the following must be true if paral
skad [1K]
You are asking for the condition needed for the 
<span>two segments to be perpendicular to each other. </span>

<span>If the slope of one segment is m, then the slope of a perpendicular segment would be -1/m </span>

<span>this means that m2 = -1/m and so m2 x m = -1 </span>

<span>If you look carefully at your choices, the 3rd answer involves the two slope and has the -1. It's </span>
<span>the correct answer.</span>

0.2 repeating is 0.2222222222...
so you have to put the repeating digit(s) divided by 9's
Then it will be 2/9 which yields 0.222222222.....
