Step 1: Identify angles subtended by the same arc. • Angles subtended by arc CD: CAD = 20^ and CBD = y^. Therefore, y = 20^. • Angles subtended by arc AB: ADB = 64^ and ACB = x^. Therefore, x = 64^. • Angles subtended by arc BC: BAC = w^ and BDC = z^. Therefore, w = z. Step 2: Use the right angle property. The symbol at BCD indicates that $ BCD = 90
