Question

find the angles that complete the equation:

\\\sin(\\_\\_\\_) = 0.9397\\

select all correct angles.

  • \\(110^\circ\\)
  • \\(70^\circ\\)
  • \\(131^\circ\\)
  • \\(49^\circ\\)
  • none of the above

Explanation:

Calcular el ángulo principal usando la función inversa

$$ \theta_1 = \arcsin(0.9397) \approx 70^\circ $$

Encontrar el segundo ángulo en el segundo cuadrante

$$ \theta_2 = 180^\circ - \theta_1 \approx 180^\circ - 70^\circ = 110^\circ $$

Verificar las opciones dadas

Los ángulos que satisfacen la ecuación son \(70^\circ\) y \(110^\circ\).

Answer:

  • (A) \(110^\circ\) (Correct answer)
  • (B) \(70^\circ\) (Correct answer)
  • (C) \(131^\circ\)
  • (D) \(49^\circ\)
  • (E) None of the above
