To find the distance across a river, a surveyor chooses points A and B, which are 197 ft apart on one side of the river. She then chooses a reference point C on the opposite side of the river and finds that A = 47° and B = 70°. Approximate the distance from A to C. a. 207 ft. b. 217 ft. c. 278 ft. d. None of the given

10. A scalar is 30 cm long. That amount in inches is: Select one: a. 11.81 inchesb. 13 inchesc. 1.81 inchesd. 5 inches 11. A car moves in a straight line 20 miles due north, then travels 10 miles due east. The trip displacement of the car was: Select one: a. 2,236 milesb. 22.36 milesc. 24.36 milesd. 223.6 miles

Please answer both

1. What is the magnitude of the resultant? 2. What is the angle describing the direction of the resultant relative to the positive x-axis?

Vector A (in the first quadrant) is 20m long and it makes an angle of 30° with the x-axis. Vector B (in the second quadrant) is 10m long and makes an angle of 35° with the y-axis. A) Find the components of these two vectors B) Use the components to find the components of the sum of the two vectors C) Use what you found in the second part to find the magnitude of the sum D) Also find the components, magnitude and the direction of 3vectorA-vectorB
