Find mDE. Round your answer to the nearest hundredth.

Answer:
[tex]50.04[/tex]
Step-by-step explanation:
Use this formula for arc length
[tex]2\pi \times r( \frac{x}{360} )[/tex]
where r is the radius and x is the arc measure.
We know Arc de is 8.73 so we are finding x.
R equal 10.
[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]
[tex]20\pi \times x = 3142.8[/tex]
[tex]x = \frac{3142.8}{20\pi} [/tex]
x=50.04
The value of the angle will be 50.04.
It is given in the question that
The arc of the circle A=8.73 In
The radius of the circle =10 In
Now from the formula of arc
[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]
[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]
[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]
[tex]\theta=50.04[/tex]
Thus the value of the angle will be 50.04
