Answer:

BC = 5 cm (nearest whole number)

Explanation:

Use the sine trig ratio:


\mathsf{\sin \theta=(opposite\ side)/(hypotenuse)}

Given:


  • \theta = 22.6°
  • side opposite the angle = a
  • hypotenuse = 13

Substituting these values into the sine ratio formula:


\implies \mathsf{\sin (22.6)=(a)/(13)}


\implies \mathsf{a=13\sin (22.6)}


\implies \mathsf{a=4.995839195...}

Therefore, BC = 5 cm (nearest whole number)
