    trigonometry triangle

    Sorry, Im in a rush I didnt draw a triangle this time [lol] but i have to find the area of this triangle

    b=146.2 c= 209.3 A=62.2

    I did:

    Area= 1/2(209.3)(146.2)SiN(62.6) = 13533.94

    It looks wrong to me though, since the number appears large...

    I used Heron's formula here, but i get the same answer as you do:

    Solving Triangle Methods

    Same relation as last problem. (A,B,C) = (1,2,3)
