Answer 2

Answer:

A. 140

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the value of z.

Upon looking at our given circle we can see that z is the intercepted arc to the inscribed angle that measures 70 degrees.

We know that measure of intercepted arc of a circle in two times the measure of inscribed angle.

Using inscribed angle theorem we can set an equation as:

$z^{\circ}=2\times 70^{\circ}$

$z^{\circ}=140^{\circ}$

Therefore, the value of z is 140 and option A is the correct choice.
