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

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

Givens:

Every triangle's interior angles add up to 180°

The triangle has a right angle.

The triangle is isosceles (two equal sides and two equal angles)

Let's make an equation with the information we have already.

2 × (2x + 3) + 90 = 180

4x + 6 + 90 = 180

4x + 96 = 180

4x = 84

x = 21
