What is the area of a rhombus that has a side of 10inches and an angle of 60 degree.

5 squ root 3
50 squ root 3
15 squ root 3
25 squ root 3

Help please!!

Just use absin({\theta})

a=b=10 and theta = 60

The answer is 50 square root 3.

The above guy is right by the way. Sin 60 times 10 times 10 = 86.6025

50 Square Root 3 = 86.6025

Plus, I'm a high school Math Teacher with a Bachelors degree in Mathematics. You can take my word for it, or fail. :)

Thank you guys very much.
