Right Kwanga, let's go. To determine the size of CKD, you'll need to find the gradients of the lines CK and KD. Step 1: Find the coordinates of point K. • K is the intersection of the diagonals AC and BD. • From question 3.2, you should have calculated the gradient of AC. Use this gradient and one of the points A(-3, -8) or C(3, 4) to find the equation of line AC. • The equation of line BD is given as y = -(4)/(3)x - 2. • Solve the equations for line AC and line BD simultaneously to find the coordinates of K. Step 2: Calculate the gradients of CK and KD. • Use the coordinates of C(3, 4), K (from Step 1), and D(3, -6) to find m_CK and m_KD. Step 3: Use the formula for the angle between two lines. • If m_1 and m_2 are the gradients of two lines, the angle between them is given by: = | (m_1 - m_2)/(1 + m_1 m_2) | • Substitute m_CK and m_KD into this formula to find CKD.
