It is 9/4π ft².
Since the central angle is 40°, this is 40/360 = 1/9 of the circle.
The area of the circle is given by A=πr²; since r=9/2, we have
A=π(9/2)² = 81/4π
Multiplying this by 1/9,
81/4π(1/9) = 81/36π = 9/4π
<em>Answer:</em>
<em>The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.
</em>
<em>
</em>
<em>The equation −
2
( x + 3 ) = −
2
x − 6 does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.
</em>
<em>
We have −
2
( x + 3 ) means that each term inside the parenthesis should be multiplied with −
2
, i.e.</em>
<em>
−
2
( x + 3
) = −
2 ⋅ x − 2 ⋅ ( + 3
) = −
2
x − 6
</em>
<em>
</em>
<em>Which is exactly what the right side says.

</em>
<em>Any value of x will, therefore, fulfill this equation.</em>

Answer:
x = 22.1°
Step-by-step explanation:
Angle ∠A = 41.124° = 41°7'26" = 0.71775 rad
Angle ∠B = 22.075° = 22°4'31" = 0.38528 rad
Angle ∠C = 116.801° = 116°48'4" = 2.03856 rad
