I need help with geometry:
nikklg [1K]

Answer:

x = 5

Step-by-step explanation:

6/18 = x/(20-x)

1/3 = x/(20-x) Multiply both sides by 20-x

(20-x)/3 = x Multiply both sides by 3

20-x = 3x Add x in both sides

20 = 4x Divide both sides by 4

5 = x

Quadrilateral PQRS is transformed by translating it 6 units to the right and then rotating it 90° clockwise
Elina [12.6K]

Answer:

(y, -x -6)

Step-by-step explanation:

<em>The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)</em>

<em />

The first transformation: 6 units right

(x,y) -> (x + b, y)

Where b = 6

So, the new coordinates will be

(x + 6, y)

The second transformation: 90° clockwise

(x,y) -> (y,-x)

So, the new coordinates will be

(x + 6, y)-> (y, -x -6)

<em>Hence, the new coordinates of PQRS is (y, -x - 6)</em>
