PLEASEE help!! “Move the horizontal and vertical sliders to stretch the image of the triangle. When you’ve settled on a pair of transformed images, record the coordinates of the imagines in the table. Be sure to list coordinates in both the horizontal (x) and vertical (y) directions. Also record the scale factors, nx and ny. Do this at least three times to fill the table.
(sorry for the bad quality haha)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

idk

step-by-step explanation:

nope

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
