<h3>Answer:  w = 31</h3>

===================================================

Explanation:

For any triangle, the interior angles always add to 180

(angle1)+(angle2)+(angle3) = 180

(w) + (4w-6) + (w) = 180

(w+4w+w) - 6 = 180

6w - 6 = 180

6w - 6+6 = 180+6 .... adding 6 to both sides

6w = 186

6w/6 = 186/6 ..... divide both sides by 6

w = 31

------------------------------------

Extra info:

This value of w leads to

4w-6 = 4*31-6 = 118

The three angles of the triangle are: 31, 118, 31

Because we have two congruent angles, this means the triangle is isosceles. The sides opposite the congruent angles are the same length.

Scrat [10]
Mike has 78 feet of fencing available for his garden, this is the perimeter (P) of the rectangle:
Perimeter: P=78 feet

The formula of Perimeter is:
P=2(W+L), where W is the width and L is the length, then:

P=78→2(W+L)=78
Dividing both sides of the equation by 2:
2(W+L)/2=78/2
W+L=39

If the shape is of a golden rectangle, we know:
L=1.6W
Replacing this above:
W+1.6W=39
Adding similar terms:
2.6W=39
Solving for W
2.6W/2.6=39/2.6
W=15 feet

L=1.6W=1.6(15)→L=24 feet

Answer: T<span>he dimensions of the garden are: Width=15 feet and Length=24 feet. </span>
