Given:
In the circle, and .
To find:
The following measures:
(a)
(b)
Solution:
According to the central angle theorem, the central angle is always twice of the subtended angle intercepted on the same same arc.
In a cyclic quadrilateral, the opposite angles are supplementary angles.
UVWX is a cyclic quadrilateral. So,
[Opposite angles of a cyclic quadrilateral]
Now,
[Opposite angles of a cyclic quadrilateral]
Therefore, and .
Since 3.805 can be rounded to 3.81, and since all other statements are false, the answer is D
To turn 0.44 into a fraction
mutiply 0.44 by 100, since there's two numbers after the decimal point
0.44 = 44/100
and to reduce that, you have to divide the whole fraction by 4
which will end up with 11/25
final answer = 11/25
