Answer:

Step-by-step explanation:

You know an angle, the side opposite the angle, and the side between them.

Use the Law of Sines.

j3 = arcsin(2.7sin(j1)/4.2) ≅ 27.0°

j2 = 180°-j1-j3 ≅ 108.0°

x = distance from j1 to j2

= 4.2sin(j2)/sin(j1)

≅ 5.7 miles

Hope this helps!

A local bakery buys their flour in bulk. The relationship between the cost of the flour and its weight is shown in the graph bel
Nataly [62]
The relationship shown for the flour and the cost is that of a direct variation because the graph is a straight line, noting that the increase of one variable causes also the increase to the value of the other. The point (1, 0.75) means that every pound of flour costs 0.75 dollar. From the graph given, the bakery will have to pay approximately $30 for 40 pounds of flour.
