Gelneren [198K]3 years ago
4 0

Step-by-step explanation:

the law of sines :

a/sin(A) = b/sin(B) = c/sin(C)

with the sides being opposite to the angles.

so,

14/sin(80) = x/sin(60)

x = 14×sin(60)/sin(80) ≈ 12.3cm

Which number line represents the solution set for the inequality <br> 3(8-4x) &lt; 6(x-5) ?
viktelen [127]

Answer:

Second number line(from top to bottom).

Step-by-step explanation:

We are given the following inequality:

3(8 - 4x) < 6(x - 5)

It is solved similarly to an equality, so:

24 - 12x < 6x - 30

-18x < -54

Multiplying by -1, the signal changes from < to >. So

18x > 54

x > \frac{54}{18}

x > 3

Thus the correct answer is given by the second number line.
