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 .
Answer:
x is 24°
Step-by-step explanation:
angles substended by the same chord or arc....90-66= 24°.
to do this just divide 9.56 by 4 to get $2.39
