Answer:
a= 73.2
b =36.6
c = 76.2
Step-by-step explanation:
Perimeter of the triangle is the distance round the triangle.
Let the 3 sides be a, b and c
Side a of the triangle is twice as long as side b. This means
a = 2b
Side c is 3 feet longer than side a. This means
c = a + 3
The perimeter of the triangle is 93 feets. Formula for finding the perimeter of the triangle is
(a + b + c)/2
Therefore,
93 = (2b + b + 2b + 3)/2
93 = (5b + 3)/2
5b + 3 = 93 × 2 = 186
5b = 186 - 3 = 183
b = 183/5 = 36.6
a = 2b = 2 × 36.6 = 73.2
c = a + 3 = 73.2 +3 = 76.2

Answer:
3/4
Step-by-step explanation:
XZ = 8 and X'Z' = 6
To find the dilation you have to divide them
6 ÷ 8 = 3 ÷ 4 = 0.75

Answer:
3. A quadrilateral with each side length 4 cm
Step-by-step explanation:
We need to understand what is a unique polygon?
<em>It means all regular polygons with the same number of sides are similar.</em>
1.A triangle with angles 30 degrees, 60 degrees, and 90 degrees
It is an right triangle, so the 3 sides are not simillar, so it is wrong
2. A triangle with side lengths 5 cm, 4 cm, and 3 cm
It is a triangle with the 3 sides are not simillar, so it is wrong
3. A quadrilateral with each side length 4 cm
It is an square with the 4 sides are simillar, so it is true
4. A triangle with side lengths 7 cm and 8 cm and a 40-degree angle
It is a triangle with the 3 sides are not simillar, so it is wrong
Hence, we choose 3.
