Finding the Coordinates of the Point Where an Arc Blends Into a Line

Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.

In this learning activity you'll apply the Law of Sines in the solution on an oblique triangle when provided with two angles and the side opposite one of the angles.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.
