What is the value of angle x°?

erastova [34]

Answer:

$64^\circ$

Step-by-step explanation:

Please refer to the attached figure for the labeling and construction in the given figure:

Given that minor angle of arc AB is $116^\circ$ .

Or in other words, we can say that angle subtended on the center O by the arc is $116^\circ$ .

Now, PA and PB are the tangents so, if we join the center of circle O with A and B, the angles formed are right angles.

i.e.

$\angle PAO = 90^\circ\\\angle PBO = 90^\circ$

Now, we know that sum of internal angles of a quadrilateral is equal to $360^\circ$ .

Here, we have the quadrilateral AOPB.

$\therefore \angle PAO +\angle PBO+\angle AOB +\angle APB=360^\circ\\\Rightarrow 90+90+116+x=360^\circ\\\Rightarrow x = 360 - 180 - 116\\\Rightarrow x = 64^\circ$

Hence, the correct answer is:

$x = 64^\circ$
