Respuesta :

The measure of the value of arc ab for angle p is 18

Answer:

Option C.

Step-by-step explanation:

Given information: Line PA and PB tangent to the circle, [tex]\angle P=36^{\circ}[/tex].

Draw the radius from the point A and B.

The tangent to a circle is perpendicular to the radius at the point of tangency.

[tex]\angle PAO=\angle PBO=90^{\circ}[/tex]

OAPB is a quadrilateral and the sum of all interior angles of a quadrilateral is 360°.

[tex]\angle AOB+\angle PAO+\angel APB+\angle PBO=360[/tex]

[tex]\angle AOB+90+36+90=360[/tex]

[tex]\angle AOB+216=360[/tex]

Subtract 216 from both sides.

[tex]\angle AOB=360-216[/tex]

[tex]\angle AOB=144[/tex]

The measure of arc AB is 144°.

Therefore, the correct option is C.
