FeatureLesson Geometry Lesson Main 1. If AB = 3x + 11, BC = 2x + 19, and CD = 7x – 17, find x. 2. If m BAD = y and m ADC = 4y – 70, find y. 3. If m ABC.
Warm Up Find the missing side. In the diagram, ΔABC is equilateral, CD is an altitude, and AC = 12. What relationship exists between Δ ADC and Δ BDC?
