Respuesta:
The condition is that angle is in betwen the two sides
1.- First using cosines law , we'll find the third side
2.- Usin the Area Heron's formula we'll find the area
Explicación paso a paso:
1.- If you know "a" and "b" and the angle γ ( oposite to side c )
c = √ a² + b² - 2ab cos γ
2.- Area Heron's formula is :
A = √ s ( s - a ) ( s - b ) ( s - c ) s = ( a + b + c ) / 2
