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 °

Answer:
x = 25; both labeled angles are 65º
Step-by-step explanation:
To find the value of x, recall that the angles formed by two parallel lines on the same line are equal if they correspond to each other.
In the figure given above, we have two parallel line given. The angle formed by each parallel line is corresponding to the other. Therefore, both angles formed are equal.
Thus,
(3x - 10)° = (x + 40)°
Solve for x
3x - 10 = x + 40
Subtract x from both sides
3x - 10 - x = x + 40 - x
3x - x - 10 = x - x + 40
2x - 10 = 40
Add 10 to both sides
2x - 10 + 10 = 40 + 10
2x = 50
Divide both sides by 2
2x/2 = 50/2
x = 25
*Plug in the value of x to find the measure of each labelled angles:
(3x - 10)° = 3(25) - 10 = 75 - 10 = 65°
(x + 40)° = 25 + 40 = 65°
