$A = {32.9}^{o}$ $A=32.9^o$

Explanation:

In $\frac{sin A}{14} = \frac{{sin 104}^{o}}{25}$ $sinA/14=sin104^o/25$

as ${sin 104}^{o} = 0.9703$ $sin104^o=0.9703$ - using tables or scientific calculator, however note that ${sin 104}^{o} = sin (180^{o} - 76^{o}) = {sin 76}^{o}$ $sin104^o=sin(180^o-76^o)=sin76^o$

we have $\frac{sin A}{14} = \frac{0.9703}{25}$ $sinA/14=0.9703/25$

and $sin A = 14 \times \frac{0.9703}{25} = 0.5437$ $sinA=14xx0.9703/25=0.5437$

and again using tables or scientific calculator

$A = {32.9}^{o}$ $A=32.9^o$
