Question

Please help fast! C=?

Answer 1

Answer:

Step-by-step explanation:

By the law of Sines,

$\frac{\sin 88^{\circ}}{26}=\frac{\sin C}{21}\\\sin C=\frac{21 \sin 88^{\circ}}{26}\\C=\sin^{-1} \left(\frac{21 \sin 88^{\circ}}{26} \right) \approx 54^{\circ}$

However, it follows that $C \approx 126^{\circ}$ must also be a solution.
