First we find the measurement of dark dot .

ANd for that we have to use the formula of the angle formed by the intersection of chord .

Let the dark dot be t.

So we have

$t =\frac{1}{2} (96+66)=81$

t and z are linear pair and sum of angles of linear pair =180 degree.

So we get

$t+z=180 \\ 81+z =180 \\ z = 180-81 =99 degree$

Why is f(x)=0 the only odd and even function?

kupik [55]

F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.

f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
