Answer:
Step-by-step explanation:
option D is the correct answer.
Given , /_ABC = 25°.
To find : angle AOC.
we know that, tangent drawn from the circle is perpendicular to center :
/_C=/_A Tangents subtends equal
angle at the center]
let, BAOC be an quadrilateral.
therefore
_B +/_A+/_O +/_C = 360° [angle sum
property of a quad.]
=>1_0+ 25+90+90 = 360°
=> LO +205 = 360°
=> /_0 = 360° - 205 = 155*
therefore, /_AOC = 155°.
