Answer:
Perimeter of the windows is P = 4s, or (here) P = 4(x+9) ft.
Step-by-step explanation:
If the area of the square is x^2 + 18x + 81 (ft^2), then the length of one side is given by the square root of that, and is x + 9 (ft). Note that (x + 9)^2 = x^2 + 18x + 81.
The perimeter of a square window of side length s is P = 4s.
Here, the perimeter of the square is P = 4(x+9) (ft).

<u>The </u><u>angles </u><u>of </u><u>the </u><u>quadrilateral</u><u> </u><u>are:</u>
- <u>8</u><u>5</u><u>°</u>
- <u>5</u><u>8</u><u>°</u>
- <u>1</u><u>4</u><u>8</u><u>°</u>
- <u>6</u><u>9</u><u>°</u>
Step-by-step explaination:
The above figure is a quadrilateral.
Hence, the angle sum of the shape is 360°.
Therefore,








Multiplying 3 by a smaller number gives a smaller product.
1/10 is smaller than 10, so 3·(1/10) is smaller than 3·10.
Answer:
x=70
Step-by-step explanation:
The value of x is 70 because this triangle is isosceles, meaning that there are two congruent sides and two congruent angles (which are the base angles). x is one of the base angles, 70º is the other base angle's measurement, so x=70.
