Answer:
41.8°
Step-by-step explanation:
Resolvemos esta pregunta usando la regla del seno
a / sin A = b / sin B
Estamos despejando el ángulo B
Por lo tanto:
3 / sin 30 = 4 / sin B
Cruz multiplicar
3 × sin B = sin 30 × 4
sin B = sin 30 × 4/3
B = arco sin [sin 30 × 4/3]
B = 41.81031 °
Aproximadamente = 41.8 °
The 2nd number line model represents 1 + ( -3 ).
