Answer:

X = 105

Step-by-step explanation:

<u>2x</u> = 42

5

Multiply both sides by 5

5 × <u>2x</u> = 5×42

5

5 cancle 5

2x = 5 × 42

2x = 210

Divide both sides by 2

<u>2x</u> = <u>210</u>

2 2

x = 105

Find the length of RA. A. 42 B. 84 C. 14 D. 7
fiasKO [112]

Answer:

\large \boxed{\mathrm{B. \ 84}}

Step-by-step explanation:

LU bisects RU and UA.

RU=UA

3m+21=6m

Solve for m.

Subtract 3m from both sides.

21=3m

Divide both sides by 3.

7=m

Calculate RA.

RA=3m+21+6m

RA=9m+21

Put m = 7.

RA=9(7)+21

RA=63+21

RA=84

The floor of a gazebo is in the shape of a regular octagon. The perimeter of the floor is 72 feet. The distance from the center
Katyanochek1 [597]
The length of one side of the octagon is given by:
 L = 72/8&#10;&#10;L = 9
 Then, the apothem can be determined using the Pythagorean theorem in the following way:
 11.8 ^ 2 = (9/2) ^ 2 + a ^ 2&#10;
 Clearing to have:
 a ^ 2 = 11.8 ^ 2 - (9/2) ^ 2
 a = \sqrt{11.8 ^ 2 - (9/2) ^ 2}
 a = 10.91
 Then, the area is given by:
 A = (8) * (1/2) * (L) * (a)&#10;
 Where,
 L: length of the octagon sides
 a: apotema
 Substituting values:
 A = (8) * (1/2) * (9) * (10.91)&#10;&#10;A = 392.76 feet ^ 2
 Answer:
 
the approximate length of the apothem is:
 
a = 10.91 feet
 
The approximate area of the floor of the gazebo is:
 
A = 392.76 feet ^ 2
