Answer:
x = 3
Step-by-step explanation:
-4x-5+2x = -11
(-4x+2x)-5 = -11
-2x-5 = -11
-2x-5+5 = -11+5
-2x/-2 = -6/-2
x = 3

Answer:
3 m^2
Step-by-step explanation:
The shaded area = Area of Sector - Area of Triangle
First we find area of sector =
<em>We know the angle is 60° (vertical angles are equal) and the radius is 6, so we find the area of sector to be:</em>
Secondly, we find area of triangle (isosceles) =
where
a and b are the two sides bordering the known angle, so a=b=6, and
C is the angle which is <em>60°</em>
Now we find the area to be:
Hence, area of shaded =
Rounding to nearest whole number, area of shaded region = 3m^2
