RS = 45.9 feet

Step-by-step explanation:

Let the length of RS be represented by x. In the given triangle applying the required trigonometric function, we have;

Cos θ =

Cos 54 =

⇒ x =

      =

x = 45.9340

x = 45.9 feet.

The length of RS in the given triangle is 45.9 feet.

it is x=-4

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
