Answer:
Arc EC = 58°
Step-by-step explanation:
First, find the value of x.
m<D = ½(arc EC) => Inscribed Angles Theorem
Substitute
2x - 5 = ½(5x - 27)
Multiply both sides by 2
2(2x - 5) = 5x - 27
4x - 10 = 5x - 27
Collect like terms
4x - 5x = 10 - 27
-x = -17
Divide both sides by -1
x = 17
Find arc EC:
Arc EC = 5x - 27
Plug in the value of x
Arc EC = 5(17) - 27 = 85 - 27
Arc EC = 58°

Answer:
(2, 0)
Step-by-step explanation:
X intercept is when y = 0.
0 = -10 + 5x
5x = 10
x = 2
Answer:
Yes
Step-by-step explanation:
they are on the same plane
This circle has a sector area of 17pi/2 and a central angle of 17pi/90.
So, the whole angle of the circle would be 2pi. To find the area of a sector, you can use the formula A=R*Angle
17pi/2= R* 17pi/90
R=45
A=45^2 * pi
A=90 pi or 282.6
