Answer:
8
Step-by-step explanation:
The length of the top segment is the difference of its x-coordinates: 7-2=5.
The length of the bottom segment is the difference of its x-coordinates: 9-(-2)=11.
The length of the midsegment is the average of the lengths of the top and bottom segments:
(5 +11)/2 = 16/2 = 8
The length of the midsegment is 8.

<em>Additional comment</em>
You can check this by drawing a midline at y = 1.5. It intersects AD on the y-axis (x=0), and intersects BC at x=8. The length of the midline is the difference of those x-coordinates: 8-0 = 8.
Answer:
Step-by-step explanation:
The measure of an angle formed by a Secant and a tangent drawn from the outside point of a circle is half the difference of the intercepted arcs.


53*2 = arc CF - 41
106 = arc CF - 41
106 + 41 = arc CF

9) If two secants inside a circle, then the angle formed is equal to the half of the sum of intercepted arcs.

5x - 7 = 73
5x = 73 + 7
5x = 80
x = 80/5

Answer:

The graph in the attached figure
Step-by-step explanation:
In this problem I will assume the the function is linear
we have the point (2,1)
we know that
y increases by 4 when x increases by 1
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
so
The slope of the linear function is

Find the equation of the line in point slope form

substitute

Convert to slope intercept form
Isolate the variable y

see the attached figure to better understand the problem
8π/5 radians
