Question

please help me in solving this sum ​

Answer 1

Answer:

Step-by-step explanation:

diagonals in a rhombus are perpendicular bisector to each other

and all sides are equal

area of rhombus is 1/2 d1 d2 = 1/2 6 8 = 24

area of OCD = 24/4 = 6

area is 1/2 * b * h = 6

1/2 * OD OC = 6

Sin OCD = 0D / CD

in ACD ;

AREA =  1/2 AD DC

12 = 1/2 CD²

CD = √24           S0  sin ocd = 4 / 2 √6

                                                = 2/√6

                                                 = √2/3
