Question

diagonals AC and BD of parallelogram ABCD intersect at the point O. if OA=6.6 cm BD=10 cm and B=40°. Find angle A , OD and AC​

Answer 1

Answer:

Step-by-step explanation:

∵ When diagonal AC and BD intersect each other at point o,

then OA = OC = (1/2) AC

And OB = OD = (1/2) BD

∴ OA = 1/2 × AC = 1/2 × 12 = 6 cm

and OB = 1/2 × BD = 1/2 × 9 = 4.5 cm
