A helicopter leaves a helipad at point A. It flies 3.2km on a bearing of 128° to a checkpoint at C. It then flies 4.7km on a bearing of 066° to its base at B. Calculate the distance from the helipad to the base.

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
