Answer:

C) Rotate Counter clockwise 90º and Translate (x-2,y)

Step-by-step explanation:

1) Rotating counterclockwise 90º the \bigtriangleup JKL \Rightarrow J'(2,-4), K(5,-4), \:L(2,-2)

Rotating counterclockwise 90º rule is: (-y,x)

We'll twist the values:

\bigtriangleup J'K'L' \Rightarrow J(4,2) K(4,5), L(2,2)

Check the picture below.

2) Now we need to translate  ΔJ'K'L' following this rule (x-2,y)

to have ΔJ''K''L''

\bigtriangleup J''K''L'' \Rightarrow J''(0,2), K''(2,5), \:L''(2,2)

AB is the angle bisector of ∠CAD. Solve for x.
Sliva [168]

Answer: x=7

Step-by-step explanation:

Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7

A rectangular window is 1 meter high and 2 meters wide. What is the perimeter of the window in meters? What is it in centimeters
DIA [1.3K]
The perimeter is the total length of all sides of the shape. 

It is 1 meter + 1 meter + 2 meter + 2 meter = 6 meters

1 meter = 100 centimeter

6(100) = 600 centimeter

Hope this helps! :)
