    |dw:1434480732936:dw| a=7 b=5 A=70 I know how we get B, which is sin B 5sin 70 / 7 which is 42.20 but what or how to we get the second B ?

    What do you mean by "second B"?

    \( \frac{5\sin 70}{7} = B_1 = 42.20\) Now they stat there is a \( B_2 = 137.80\) but I do not know where that is coming from

    So you are looking for a reason why \(B_2 = 137.80\)? Can you label \(B_2\)? Where is it in triangle you sketched?

    They stat there are two angles for B 0 < B < 180

    They stat there are two angles B 0 < B < 180, for which sin B = \(\frac{5\sin 70}{7} \)= 42.20

    First angle is 42.20 how to find the other?

    That's good then. We don't know what second angle is referred to...

    To find the other angle we do 180 - 42.20

    That is how you get the second angle when doing SSA
