I wish I could help but I’m taking it right now too. I’m struggling lol
Answer:
X has an element of empty set
just know that it is always true to some extent.
Step-by-step explanation:
<span>The ratio of areas is the square of the ratio of perimeters;
The area of triangle B / The area of triangle A = 25 ;
The perimeter of triangle B / The perimeter of triangle A = </span>

The perimeter of triangle B is 5many times greater than the perimeter of<span>triangle A!</span>
Y is equal to 54. (B)
A triangle has a total degree of 180. Given that two of the angles are the same and the last angle is 72 degrees, you can subtract 72 from 180 to get 108. From there, You can divide 108 by 2 (because there are two equal parts) to get 54.
