Answer:
B = (-6, 6)
Step-by-step explanation:
If M is the midpoint of AB, then ...
B = 2M - A
B = 2(-1, 4) -(4, 2) = (-2-4, 8-2)
B = (-6, 6)
Answer:
<em>L= 9.086 feet</em>
Step-by-step explanation:
<u>Area of a Circular Sector</u>
Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by
And the length of the arc is:
We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:
Solving for θ:
The arc length is:
L= 9.086 feet
Basically, we have to solve for x to find what value makes the open sentence true.
A flat line represents 1/2 of a 360deg circle or 180deg. To find angle 3 you will need the following formula:
180-90-angle4= angle3
90-angle4= angle3
