POSSIBLE POINTS: 63.64Every triangle has three altitudes, each drawn from one of the three vertices perpendicular to the line containing the third side. In an obstuse triangle. some of the altitudes will lie outside of the triangle. Show how you can use one of the exterior altitudes in the following diagram to solve the triangle.(Hint: Find the missing side lengths of the auxiliary right triangle formed by the exterior altitude first.) In this diagram, the 6 cm measurement refers to line segment AB, the 18 degree angle is angle BCA, and angle ABC measures at 132 degrees.
