Answer:

Step-by-step explanation:
In the triangle,
Hypotenuse = 13
Opposite = Perpendicular = 5
Adjacent = Base = 12
Now,
Cos B = 
Cos B = 12/13
If the triangle is just like in the attached file!
<span>To solve a triangle using law of sines you must have the length of one side and the measure of the angle opposite that particular side. Then you must have one other piece of information, either one more side length or one more angle measurement. However in some cases when the information you are given is two consecutive sides, and the angle is not between the two consecutive sides, then there exists the possibility that there are two different triangles that will satisfy the given information.</span>

EXPLANATION
The equation of a circle given the center (h,k) and radius r is given by:

The circle has center (4,0) and radius

We substitute the center and radius to get,



Answer:
Step-by-step explanation:
place a point at (0,0)- the starting point
next point at (2,1) - in 2 minutes she is 1 block away
Next point (4,2)- in 4 minutes she will be 2 blocks away
Connect those 3 points
then place a point at (9, 2)- 5 minutes later she was still at the store
Connect points
Point at (11,1) and (12,0) and connect
