its b
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given:
Length of radius of circle = 5 feets
Length of perpendicular bisector = 4 feets
To find:
Area of the shaded portion of the circle
Solution:
As OD is perpendicular bisector of AB,


Area of
= 1/2 (base) × (height) =
square feets
Area of sector AOBC =
square feets
Here, r denotes radius of circle
So,
Area of shaded portion = Area of sector AOBC - Area of
=
C) sum of interior angles must be 180°.
This is because a straight line = 180°, so if the interior angles of a triangle = 180° they can form a straight line if arranged correctly.
Answer:
x = 17
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + x^2 = (sqrt(514))^2
225 + x^2 = 514
Subtract 225 from each side
225-225 + x^2 = 514-225
x^2 =289
Take the square root of each side
sqrt(x^2) = sqrt(289)
x = 17
