Width: 4
Step-by-step explanation:
We can create a system of equations for this problem, where is the width and
is the length.
The perimeter of a rectangle is twice its length added to twice its width.
The length is 3 more than the width:
We can now substitute in as
in the equation
.
Distribute the first terms:
Combine like terms:
Subtract 6 from both sides:
Divide both sides by 4:
Now we know that w = 4. We can now substitute this inside an equation to find .

Because the angles are supplementary, they add to 180 degrees.
I solved this by dividing
which gives me 30 degrees.
multiply 30 by 5 gives you 150.
and 30 + 150 = 180
I solved this by dividing
multiply 30 by 5 gives you 150.
and 30 + 150 = 180
