Answer:

4.5 miles

Step-by-step explanation:

We can use a ratio to solve

3 miles                 x miles

---------------  = ----------------

80 minutes         120 minutes

Using cross products

3 * 120 = 80x

Divide each side by 80

360/80 = 80x/80

4.5 =x

Answer:

2π feet

19. In the triangle ABC, the side lengths are BC = 14 and AC = 7. What's the angle measurement of B?
mr Goodwill [35]

Answer:

Is not possible to compute the angle under those conditions.

Step-by-step explanation:

You need more information, I will be more specific, there is a book called "Geometry" by Moise Downs where the following theorem is stated on the chapter 7.

Let    ΔABC   and   ΔDEF   be two triangles  where AB = DE  and AC = DF  if  

∠A   >  ∠D     then   BC > EF,   which in simple terms means that, if two sides are equal, the angle between them can vary as much as you want and that will directly imply the size of the third size of your triangle.  

Therefore, there is information missing in order to solve the question
