Question

ABCD is parallelogram in which diagonal AC and BD intersect at point O. if <bao=20°,<cod=133°,then the value of <ODC is​

Answer 1

Answer:

27°

Step-by-step explanation:

in a parallelogram ABCD,

diagonals intercept at O

given angle BAO is 20° and COD is 133°.

in parallelogram opposite sides are parallel

so consider AC as a transversal

so angle BAO is equal to angle DCO i.e 20°

so in parallelogram, in triangle ODC we have 2 angles(133° and 20°)

we know sum of all angles must be 180°

so other angle is 27°
