Answer:
the sum of two rational number is minus 4 by know if one of them is 13 by 6 them find the other
Step-by-step explanation:
let the second rational no. be x
then a/q,
13/6 + x = -4/9
x = -4/9 - 13/6
x = (-16 - 78)/36
x = - 94/36 or -47/18
x = -2.61111

Given:
A diagram of a circle O,
.
To find:
The measure of arc DC.
Solution:
According to the angle of intersecting chords theorem:
Angle at intersection of chords = Half of the sum of intercepted arcs.
Let
be the angle between the intersection of chords AC and BD.
(Linear pair)

Using the angle of intersecting chords theorem, we get



On simplification, we get



Divide both sides by 2.

Now,



Therefore, the correct option is C.
