wlad13 [49]

Answer:

Step-by-step explanation:

Sum of angles in a quadrilateral= 360 degrees

<OCA=90degrees [ tangent perpendicular to the circle.

<OBA= 90degrees =tangent perpendicular

to the circle

<OCA + <OBA +92 + <OAB= 360

90 + 90 + 92 + <OAB = 360

272 + < OAB = 360

<0AB= 360- 272 =88 degrees
