Answer: The second option (160 cm)
Step-by-step explanation:
1. You can obtain the perimeter of a quadrilateral by adding the lenghts of the sides.
2. You know that the ratio of the side lengths is 3:3:5:8 and the perimeter is 380 centimeters.
3. Therefore, you can write the following expression, where x is an integer:

4. Solve for x:

5. Therefore, the longest side is:
(160 cm)
If this paper dosent help u solve it on Your own i can walk u through it
It would be twice whatever the midsegment equals.
Answer:
x = 7
Step-by-step explanation:
move all terms that don't contain x to the right side and solve :)
3. Trapezoid- only one pair of parallel sides
4. Parallelogram- opposite sides are parallel and equal in length and opposite angles are equal
5. Rhombus- all sides have an equal length, opposite sides are parallel, and opposite angles are equal
6. Kite- have two pairs of sides, each made up of adjacent sides that are equal in length. Angles are equal where pairs meet.
7. Isosceles Trapezoid- have a pair of opposite parallel sides that are equal in length.
