Question

In adjacent figure OB perpendicular to OA . angle BOC= 52 °.Find angle AOD.?​

Answer 1

Answer:

in adjacent figure angle BOA is a right angle

it means angle AOC and angle BOC are pair of complementary angles

if m angle BOC =52°

ANGLE AOC=

angle AOC + BOC = 90°

therefore 52° + AOC = 90°

angle AOC = 90°-52°

therefore angle AOC = 38°

m angle DOA =

ANGLE DOA and angle COA are pair of spokesman angles or angles in a linear pair

if angle COA/AOC = 38°

then m angle DOA = 38° + DOA = 180°

angle DOA = 180° -38°=142°

therefore m angle DOA is 142°
