diameter = 2*radius => 2√61 =2r => r =√61 => r² =61
midpoint of the diameter is:

Answer:
A= Origen C= q1 B=Q2
Step-by-step explanation
your left-hand side is quadrant <u>TWO</u> Your top right-hand corner is Quadrant <u>ONE</u> and your second to the last one is left-hand side down Is Quadrant <u>THREE</u> last but not least is Quadrant <u>FOUR. </u> And the zero in the middle means <u><em>ORIGEN. </em></u>
Answer:
B
Step-by-step explanation:
So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.
Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.
Heres what we know however:
angle 1 + angle 2 = 180 degrees.
How do we know this?
Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.
Lets input that into our nice lil equation to get an answer:
7 degrees+angle 2 = 180 degrees
Now lets solve.
Subtract 7 on both sides, and your left with:
angle 2 = 173 degrees.
So the answer must be:
<u>173 degrees</u>
Hope this helps! ;)
Answer:
X = 49
Step-by-step explanation:
Here
4x=147+x (by alternate interior angle)
4x-x= 147
3x=147
X=49
