You’re building a rectangular frame 10 inches by 11 inches. how many feet of wood do you need?

The required feet of wood needed is 3.5 foot.              

Step-by-step explanation:

Given : You’re building a rectangular frame 10 inches by 11 inches.

To find : How many feet of wood do you need?

Solution :

According to question,

We have to find the perimeter of the rectangle,

The perimeter of the rectangle is

The perimeter of the rectangle is 42 inches.

Which means the wood required is 42 inches.

Convert inches into feet,

1 foot = 12 inches.

1 inch = foot.

42 inches =   foot.

42 inches = 3.5 foot.

Therefore, The required feet of wood needed is 3.5 foot.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
