Answer:
4. 158
Step-by-step explanation:
First let's make things a little simpler and put these arcs in terms of x. We know that the degree measure around the outside of a circle, regardless of its size, is 360. So let's say that arc BC is x. That means that arc BDC is 360 - x. This is because arc BC + arc BDC = 360. Substituting in our x's we have:
x + 360 - x = 360 and
360 = 360. (That's just the proof that putting in our x's as we did does in fact work!)
Following the formula then, we have
and
Multiply both sides by 2 to get rid of the fraction and get
44 = 360 - 2x
Subtract 360 rom both sides to get
-316 = -2x
Divide both sides by -2 to get that x = 158
Since we are looking for arc BC and we designated arc BC as our x, that means that arc BC = 158.
Answer:
The dimensions of is width: 41, length: 82
Step-by-step explanation:
Consider the provided information.
Let y is the length of side parallel to the wall and x is length of each side perpendicular to the wall.
The perimeter of rectangle is 2x + 2y since, we need to use the side of building and fencing for the other 3 sides. Therefore,
y + 2x = 164
y = 164-2x
The area of rectangle is xy.
The above equation is in the form of a quadratic equation .
The graph of the function is a parabola opening downward. As the coefficient of x² is negative. The maximum occurs at the x-coordinate of the vertex.
In order to find the vertex, use the formula
So the vertex is (41,3362).
This shows us that the max area is then 3362 square feet.
Now substitute the value of x in y = 164-2x
y = 164-2(41)=82
Hence, the dimensions of is width: 41, length: 82
