A pipe cleaner lay across a wire shelf. The wires that make up the shelf are parallel, and the pipe cleaner is a transversal. Th
e parallel wires are labeled a, b, and, c, and the angles are labeled with numbers.
The measure of one angle is 130°. Which statement is true regarding the 130° angle and angle 3?
They are same-side interior angles, so angle 3 measures 50°.
They are alternate interior angles, so angle 3 also measures 130°.
They are corresponding angles, so angle 3 also measures 130°.
They are alternate exterior angles, so angle 3 measures 50°.

1 answer:
Answer:
<h2>They are alternate interior angles, so angle 3 also measures 130°.</h2>Step-by-step explanation:
Notice that the pair of angles are inside parallels, and at different sides of the transversal. So, those angles are alternate interior angles by definition, which means they are congruent.
Therefore, the right answer is B.

Answer: Last option.
Step-by-step explanation:
Observe the diagram.
The perimeter of the parallelogram will be the sum of the lenghts of its sides. Then:
You know the lenght of the side WZ. This is:
Notice that:
Now, you must find the lenghts of the sides WX and YZ ()
Observe that WZ goes from 2 to -2, therefore its lenght is:
Therefore, substituting values, you get that the perimeter of the paralellogram is:
Answer:
The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.
Step-by-step explanation:
Assuming that the shortest side of this triangle has a length of "x" feet, then one side is "x + 4" feet and the third is "2*x - 4" feet. Since the perimeter of the deck is 80 feet, then the sum of the length of these sides should be equal to that.
The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.
