If two sides of a triangle are 12 and 17, and the included angle is 60, what is the area of the triangle

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

to complete this square you have to rotate about the origin 270 degrees clockwise.
