The slope is -1

Step-by-step explanation:

Given ABC is an isosceles right triangle in which has a slope of -1 and mABC = 90°. Now, ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'.

As we know that the slope is equal to

And also in dilation only the the length of sides increases or decreases by same factor which results in same angle i.e tan remains same.

Hence, slope never changes in dilation.

Therefore, slope is -1

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
