**Finding the Angle Between Two Vectors Using Cosine Law**

When the satellite is on one side of the two stations, the angles of elevation at A and B are measured to be 87.8° and 83.6°, respectively. Find how far the satellite is from station A and how high the satellite is above the ground.... When the satellite is on one side of the two stations, the angles of elevation at A and B are measured to be 87.8° and 83.6°, respectively. Find how far the satellite is from station A and how high the satellite is above the ground.

**Finding the Angle Between Two Vectors Using Cosine Law**

Law of Cosines The law of cosines for calculating one side of a triangle when the angle opposite and the other two sides are known. Can be used in conjunction with the law of sines to find all sides and angles.... Do you get 0.319846? If so you have your calculator set to radian mode. There should be a little indicator with d/r/g showing what mode you are in, and some setup option to change the mode. You can change the value to degrees by taking 180 * angle / pi, here this gives 18.325833862100342º. The next

**Finding the Angle Between Two Vectors Using Cosine Law**

The law of cosines is a formula that relates the three sides of a triangle to the cosine of a given angle. When to use law of cosines? There are 2 cases for using the law of cosines. What You Know What You Can Find ; Case I 2 sides and the included angle 3rd side : Case II 3 Sides of Triangle Any Angle: Why only the 'included' angle? As you can see in the prior picture, Case I states that we... When given any two vectors, it is possible to use the dot product to find the angle between the vectors without having any ambiguity as it uses the inverse cosine function.
