Answer 3

Please help XD

Answer 4

i'm eating lunch @JustSaiyan

Answer 5

@celticcat can you help?

Answer 6

Its been a long time since I did these
I believe that the coordinates change as below
x coordinate ---> y
y coordinate ----> -x

so P' would be (4 , -3)

Im not absolutely sure though

Answer 8

te translation is easier to solve
look at the y coordinates - they go down 2 units
while the x coordinates stay the same.

Answer 9

- that should give it to you

Answer 10

look at point A and A' y = -4 ---> y = -6 is a drop of 2 units down parallel to the y-axis.

Answer 11

What was the answer again?

Answer 13

a dilation of 1/2 simply means that each line is reduced to 1/2 its size
so the side length 7 changes to 1/2 * 7 which is 3 1/2

Answer 14

- so A'B' = 3 1/2

Answer 15

Okay

Answer 16

what about the 2nd and 3rd option

Answer 17

just perform the same process as with AB

Answer 21

Hint find the measure of <y
Remember that the 3 angles of a triangle add up to 180 degrees
so that m < y = 180 - 35 - 15 = ?

Answer 25

130

Answer 26

130

Answer 27

130

Answer 28

right

Now calculate the measure of <x in the other triangle
What do you notice about the measures of the angles in the 2 triangles?

Answer 29

im lost how do i do that

Answer 30

in the same way as you found y
180 - the measures of the other 2 angles

Answer 31

check the question

Answer 39

???
all the info you need is in the question
'triangle ABC has angles 130 , x and 15'.

Answer 40

well can i get the letter answer please my time is expiring

Answer 41

@celticcat

Answer 42

x = 180 - 130 - 15

Answer 43

35

Answer 44

its not clear what the letter choice is

Answer 45

now look at the values of the angles in triangles ABC and DEF
what do you notice ?

Answer 46

A

Answer 47

ABC has angles 130,15 and 35 and DEF has what ?

Answer 48

the same thing

Answer 49

right so the 2 triangles are similar
so its C

Answer 50

I hope you have learned something in this post.

Answer 51

it cant be A or B because the triangles are similar
and it cant be D because all 3 angles have to be equal for triangles to be similar
