Diamond ABCD

In the diamond ABCD, the diagonal e = 24 cm and the size of angle SAB is 28 degrees, where S is the intersection of the diagonals. Calculate the circumference of the diamond.

Correct answer:

x =  54.36 cm

Step-by-step explanation:

$x=4\cdot (24\mathrm{/}2)\mathrm{/}\cos 28\mathrm{°}=\cos 7\pi \mathrm{/}45=0=54.36\text{ cm}$
