We can solve this problem in different ways:

0. Statement: As angle 1 and 3 are vertical angles, and angle 1, 5, 4 form a straigth angle, so angle 2 and (algle 4 + angle 5) are vertcal angles too.

Reason:

$\begin{gathered} \angle1+\angle4+\angle5=180=\angle2+\angle3(share\text{ the same line)} \\ \angle1=\angle3(verticl\text{ angles)} \\ So, \\ \angle4+\angle5=\angle2 \end{gathered}$

This is found by multiplying pi by the radius squared

Minchanka [31]

Answer:

x = 94°

Step-by-step explanation:

The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is

$\frac{1}{2}$ ( arc CD + arc AB ) = 82°

Multiply both sides by 2 to clear the fraction

CD + AB = 164°, that is

x + 70 = 164 ( subtract 70 from both sides )_

x = 94°
