In order to find the value of "x", it is important to remember that:
We can identify in the figure that:
Then:
Solving for AB:
Now, since there are 360° in a circle, we know that:
Then we can substitute 
into 
and solve for "x". This is:
Answer:
Step-by-step explanation:
300 miles
125/2.5= 50 miles per hour
50*6=300
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
The length of CD is 7-3=4.
Therefore, if we dilate by a scale factor of 3, the length is 4(3) = 12
