To find the area of a sector of a circle use the next formula:
As the given circle has a outside angle 90º (it is not part of the sector of the circle) subtract the 90º from 360º (total angle of a circle) to find the angle of the sector:
Find the area of the sector with angle 270º:
Then, the approximate area of the given sector of a circle is 284.955 square inches
Answer:
The mean is 0.26
The standard deviation is 0.5765
Step-by-step explanation:
An image showing the step by step solution is attached.
Not exactly
2/10 = .2
1/4 = .25
1/4 is 0.05 bigger than 2/10
Answer:
BD does bisect the angle created by ABC, however it does not bisect segment AC. So it really depends on what you are determining the bisection to be.
Step-by-step explanation:
We can tell that it is bisecting the angle since it creates two congruent angles.
We can tell that it does not bisect the segment as AD and CD are not the same length.

x = 45°
Step-by-step explanation:
Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
