Hi, I can't seem to see the picture of the triangle...

Find the area

Obtuse scalene triangle.

Use the Law of Cosines to find the 3rd side c =5.273

Sides: a = 4   b = 7.3   c = 5.273

Once you have ALL 3 sides, then you can use Heron's Formula

to calculate the area of the triangle.[Look it up in your Textbook]

Area: T = 10.275
Perimeter: p = 16.573
Semiperimeter: s = 8.286

The third angle is 45°        (  180 - 103 - 32 = 45 )

The height of the triangle     h = sqrt(16/2) = 2.828427125

Area of the triangle        A = ( h * 7.3 )/2   =  10.323759 cm²
