Step-by-step explanation: B
put the center of the circle on the right of the line and the edge of the circle on the p. Make part of a circle. you dont have to do the whole circle, but you can if you want.
do the same thing again but on the other side of the line.
now it should look like the first image i included (if you didnt do the whole circle)
now take your straightedge/ruler/line maker and make it go through the intersecting points on the circles, like the second image.
Note that my images are for demonstration. They're not perfect at all, they're just to show you how to do it.

Answer:
rjeov oke eieie
Step-by-step explanation:
To multiply fracti0ons, we need to convert them to improper fractions:
-2 1/4 = -9/4
-4 1/2 = -9/2
Now, lets multiply:
-9/4 * -9/2 = 81/8
Hope this helps!
Take note that the answer is positive because when multiplying, two negatives make a positive.
Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and 
.
To find:
The 
.
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[Alternate interior angles]
In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[Base angles of an isosceles triangle]
In triangle AOB,
Therefore, the measure of angle AOB is 120 degrees.
