Recall that the angle's vertex is at ( 2 , 1 ) , the angle measures 1 radian and the circle centered at the vertex of the angle has a radius 1.5 units long. The terminal point is how many radii to the right of the circle's center? Incorrect radii Incorrect Try again. Try using the cosine function. The terminal point is how many units to the right of the circle's center? Incorrect units Incorrect Try again. The circle's radius is 1.5 units long, and your answer to part (a) tells you how many radius lengths the terminal point is to the right of the circle's center. Since the circle's center has an x -coordinate of x = 2 , what is the x -coordinate of the terminal point? x = Incorrect Incorrect Try again. The circle's center is x = 2 units to the right of x = 0 , and part (b) tells you how much further the terminal point is to the right of that. Get help: Video
