(16)/(sin(a))=(12)/(sin(31))

\frac{16}{sin ( a )} = \frac{12}{sin ( 3 1 ^{\circ} )}

a = 0.75696 \dots + 36 0^{\circ} n, a = 18 0^{\circ} - 0.75696 \dots + 36 0^{\circ} n

Solution steps

\frac{16}{sin ( a )} = \frac{12}{sin ( 3 1 ^{\circ} )}

Cross multiply

16 sin (3 1^{\circ}) = sin (a) \cdot 12

Switch sides

sin (a) \cdot 12 = 16 sin (3 1^{\circ})

Divide both sides by

12

sin (a) = \frac{4 sin ( 3 1 ^{\circ} )}{3}

Verify Solutions

Find undefined (singularity) points:

sin (a) = 0

Combine undefined points with solutions:

sin (a) = \frac{4 sin ( 3 1 ^{\circ} )}{3}

Apply trig inverse properties

a = arcsin (\frac{4 sin ( 3 1 ^{\circ} )}{3}) + 36 0^{\circ} n, a = 18 0^{\circ} - arcsin (\frac{4 sin ( 3 1 ^{\circ} )}{3}) + 36 0^{\circ} n

Show solutions in decimal form

a = 0.75696 \dots + 36 0^{\circ} n, a = 18 0^{\circ} - 0.75696 \dots + 36 0^{\circ} n

tan (x) = \frac{25}{10}

sin (x) - 1 = 0, 0 \leq x < 2 π

3 cos (θ) = 2 cos (θ)

\frac{26.4575}{sin ( 6 0 ^{\circ} )} = \frac{20}{sin ( B )}

sin (\frac{5}{2} θ) = - 0.966
