0.05 because 5 is bigger than 4 plus 4 is negative
Step-by-step explanation:
the correct formula for this is the heron's formula
which states that s=√s(s-a)(s-b)(s-c). Where s is a+b+c all divided by 2
s=√(13.5-12)(13.5-9)(13.5-6)
s=√(1.5)(4.5)(7.5)
s=√50.625
s= 7.11 or 7 to the nearest square unit
<h3>
<u>Explanation</u></h3>
- Given the system of equations.

- Substitute y = -4x in the second equation.

- Substitute the value of x in any given equations. I will substitute the value of x in the first equation.

- Answer Check by substituting both values in two equations.
<u>First</u><u> </u><u>Equation</u>

<u>Second</u><u> </u><u>Equation</u>

Both equations are true for the value of x and value of y.

Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,



We know that, area of a sector is

Where,
is central angle, r is radius.




Multiply both sides by 360 degrees.


The value of x is 60 degrees.
Therefore, the correct option is A.
