Answer:
28 feet
Step-by-step explanation:
We know that the perimeter of a square is
, where l is the length and w is the width.
We also know that the perimeter of a triangle is all of its sides added up.
Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.
Basically:

We can combine like terms to get a <em>less scary</em><em> </em>equation.

Our goal is to now isolate x so we can find it's value.
Add 2 to both sides:

Subtract 6x from both sides:

Add 10 to both sides:

Divide both sides by 2:

Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.
Let's do it on the triangle.
(remember, this is our simplified version of the triangle)

Hope this helped!
Secθ = cos^(-1)θ is the same as secθ = 1/cosθ
<span>Secant is a trigonometric function, reciprocal to the cosine. </span>
<span>People get confused because they tend to link "cosine" and "cosecant" (which is reciprocal to the sine)</span>
Answer:
No
Step-by-step explanation:
No, the law of sines cannot be used to solve the triangle. The triangle shows the measures of two sides and an included angle. To use the law of sines, you need to know the measure of an angle and its opposite side.

Answer:
12
Step-by-step explanation:
h(x) = f(g(x))
Using chain rule:
h'(x) = f'(g(x)) g'(x)
h'(1) = f'(g(1)) g'(1)
h'(1) = f'(2) g'(1)
h'(1) = -4 × -3
h'(1) = 12
