Answer:(theta) =π only
Step-by-step explanation:
-4cos(theta)+1=5
Subtract 1 from both sides
-4cos(theta)+1-1=5-1
-4cos(theta)=4
Divide both sides by -4
-4cos(theta) ➗ -4=4 ➗ -4
cos(theta)=-1
(theta)=cos(inverse)(-1)
(theta)=180
(theta)=π
Let's call the width 
and the length 
based on this, we can make two equations based on the first and second sentences in the problem.
If we substitute 
for into the second equation, we can make the following:
- Use the Distributive Property
- Subtract 4 from both sides
- Divide both sides by 4 and simplify
Now, let's find :
The length of the rectangle is 
and the width of the rectangle is 
.
Answer:
9.
Step-by-step explanation:
You would have to find the area of the triangle which is 1/2(bh) which would give you 9. So you would 9 feet of outdoor carpet. Which is actually already given to you as the area inside the triangle.
Answer:
perimeter= 28
area=33
