Answer:
In the given circle, segments OA, OB, OC and OD are radius of the circle.
In other words, all those segments are congruent.
From that we can deduct that triangles OAB and OCD are isosceles triangles, because all segments are equal. That makes those triangles congruent, because they have the same sides.
From the congruence we can deduct that all corresponding internal angles inside those triangles are actually congruent, that's why angle OAB and ODC must be congruent.
Also, angles DOC and BOA are also congruent, which means their subtended arcs are also congruent, because they have the same radius, so mAB = mCD.
The answer to that would be 97.
Hope this helps! :)
5 2/5 would be converted to 5 6/15. you would then subtract the numerators and the whole numbers, giving you 3 5/15, which simplifies to 3 1/5

Answer:
x = 6√3
Step-by-step explanation:
Let's just look at the right triangle. This is a 30° 60° 90° triangle. The value of the large leg (x) will be the value of the small leg times √3. The value of the hypotenuse (12) is the value of the small leg times 2. Since we know that, we can divide 12 by 2 to find out the value of the small leg will be 6. Finally, know that we know that 6 is the value of the small leg, we can multiply 6 by √3 to find that the value of x = 6√3.
