Uhh, answer choices?
In any case, since
is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem,
Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so 
Answer:
360 hours
Step-by-step explanation:
When trying to find the number of hours out of the number of days someone has been doing something, assuming that she spent all 15 days traveling with no rest, you just multiply however many days (In this case, 15 days) by 24 hours.
This gives us the equation 15 times 24, which then equals 360.
A way I check these is that I divide however many hours I got by 24 and make sure it equals our first number.
We get the equation 360 divided by 24, which does, in fact, equal 15.
Answer: -8/11 or -.72727...
The angle for x is 180 degrees because it is at the part of the circle that is straight up and down
Answer is 3,3
since x does not contain a variable move it to the right by subtracting x from both sides and multiple secou d equation by -1
y=-x+6
y=x
