Question

11. In Figure 8. ABCD is a rhombus whose diagonals AC and BD intersect at O. If OAB:OBA = 3:2, find the measure of all the angles of triangle COD.​

Answer 1

Answer:

According to quesion,

AB=10, BD=16

From figure,

AO+OC=AC

& AO=OC

=> 2AO=AC

In △AOB, from pythagorous

AB

2

=AO

2

+BO

2

=> 100=64+AO

2

=> AO=6

Since, AC=2OA,

Hence, AC=12cm

solution

this is the answer
