270° around the origin

Step-by-step explanation:

As shown at the graph

ΔABC is translated to ΔA'B'C'

A(0,3) , B(-2,2) , C(-1,1)

A'(3,0) , B'(2,2) , C'(1,1)

So, if the coordinate of the pre-image is (x,y)

The coordinate of the image will be (y, -x)

Which mean the rule will be (x,y)→(y,-x)

The previous rule is the rule of rotation 270° counterclockwise

So, the answer is 270° around the origin

If angle 4 is 52.7, what are the measures of angles 1,2, and 3?

shusha [124]

Answer:

127.3
52.7
127.3
52.7

Step-by-step explanation:

Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).

52.7 + x = 180

x = 127.3

Best of Luck!

What are the common factors of 18 and 30? What do they represent?

Zolol [24]

Factor out 18.

The factors for 18 are as listed:

1, 2, 3, 6, 9, 18

Now factor out 30.

The factors for 30 are as listed:

1, 2, 3, 5, 6, 10, 15, 30

Now look at the factors that are both factors for 18 and 30.

So, the common factors are 2, 3, and 6.
