That would be a true statement according to the lettered points. If you’ll notice, all the way around the figure, the letters are in that order. Therefore, yes it qualifies as a rectangle.

The perimeter of a fence must be no larger than 500 feet in length. The longer side of the fence must be 10 feet more than twice

Lady bird [3.3K]

Answer:

<em>The shortest side of the fence can have a maximum length of 80 feet</em>

Step-by-step explanation:

<u>Inequalities</u>

To solve the problem, we use the following variables:

x=length of the longer side

y=length of the sorter side

The perimeter of a rectangle is calculated as:

P = 2x + 2y

The perimeter of the fence must be no larger than 500 feet. This condition can be written as:

$2x + 2y \le 500$

The second condition states the longer side of the fence must be 10 feet more than twice the length of the shorter side.

This can be expressed as:

x = 10 + 2y

Substituting into the inequality:

$2(10 + 2y) + 2y \le 500$

This is the inequality needed to determine the maximum length of the shorter side of the fence.

Operating:

$20 + 4y + 2y \le 500$

Simplifying:

$20 + 6y \le 500$

Subtracting 20:

$6y \le 500 - 20$

$6y \le 480$

Solving:

$y \le 480 / 6$

$y \le 80$

The shortest side of the fence can have a maximum length of 80 feet

What is the m<2 = ?

Degger [83]

Answer:

m∠2=9

Step-by-step explanation:

Hello There!

The problem states that the angles are complementary angles

Complementary angles are angles that have measures that add up to equal 90

So given one of the angles we can find the missing angle by subtracting the known angle from 90

90 - 81 = 9

so we can conclude that the measure of angle 2 is 9
