    Sin A= 12/13 Therefore p=12 and h=13 b2 = h2-p2 b2= (13)2 -(12)2 b2=169-144 b2=25 b= root25 b=5 Hence cos A= b/h=5/13 tan A=p/b=12/5

    Given sin A=12/13 ie. Opposite/Hypotenuse Then By Pythagoras theorem AC^2=AB^2+BC^2 13^2=12^2+BC^2 169=144+BC^2 169-144=BC^2 √25=BC 5=BC cos A = Adjacent side/Hypotenuse cos A=5/13 tan A= 12/5

    1Thank You
