Question

In the figure, what is the value of x?

Answer 1

1. C 2. B 3. D 4. B 5. C

Answer 2

Answer:x=90 °

Explanation:

In any circle the exterior angle formed is half of the major arc - minor arc .

Angle formed by tangents or secants =
`(1)/(2)(Major arc - minor arc )`

The sum of measure of arcs inany circle is 360°.

Minor arc is given as x°.So Major arc = 360-x.

Substituting the given values in the formula :

`x=(1)/(2)(360-x-x)`

`x=(1)/(2)(360-2x)`

x=180-x

Adding x both sides we have:

2x=180.

Dividing both sides by 2.x= 90.
