Answer:

k = 4 \sqrt{3}

The last answer is correct

Step-by-step explanation:

We know that,

\tan(60)  =  \sqrt{3}

So, to find the value of k we can use the tan rule

\tan(60)  =  \frac{o}{a}  \\  \sqrt{3}  =  \frac{k}{4}  \\ k = 4 \sqrt{3}

Hope this helps you

A rectangular family room is 18 feet long and 14 feet wide.
Firlakuza [10]

Answer:

4 pieces of chair rail are needed

Step-by-step explanation:

<u>Step 1: Calculate the perimeter of the room</u>

Perimeter of rectangle = 2L + 2B

Length = 18

Breadth = 14

Perimeter of room = 2(18) + 2(14)

Perimeter of room = 64 feet

<u>Step 2: Calculate the pieces of chair rail needed</u>

<em>Perimeter of room = 64 feet</em>

<em>Length of each chair rail = 16 feet</em>

<em>Total chair rails needed = Perimeter of room/length of each chair rail</em>

<em>Total chair rails needed = 64/16</em>

Total chair rails needed = 4

Therefore, Mr. Herzog needs 4 pieces of chair rails.

The sum of three consecutive natural numbers is 1146, find the numbers.
-BARSIC- [3]

\text{Let the 3 consecutive numbers be}~ x,~x+1~ \text{and} ~x+2.\\\\\text{According to the condition,}\\\\x+x+1+x+2 = 1146\\\\\implies 3x +3 = 1146\\\\\implies 3(x+1) = 1146\\\\\implies x+1 = \dfrac{1146}3 = 382\\\\\implies x= 382-1 = 381\\\\\text{Now, the numbers are}~ 381,~382~\text{and}~383
