In a ` A B C ,` prove the following : In a ` DeltaA B C ,\ if\ a=5, m\ b=6\ a n d\ C=60^0,` show that its area is `(15sqrt(3))/2` sq.units`dot`

Text Solution

Verified by Experts

Given : `a=5,b=6,c=60^o`
Area of the triangle= `1/2 ab Sin C`
`1/2 times 5 times 6 times sin60^o=15 times sqrt3/2sq.` units
Hence proved
