Just as you saw Triangle A B D used to create an equation for c2, use Triangle C B D to create an equation for a2. Solve this equation for h2. ✔ h2 = a2 - x2X h2 = a2 + x2x2 = a2 + h2

Replace your expression for h2 in c2=h2+b2-2bx+x2.✔ C2 = a2 - x2 + b2 - 2bx + x2c2 = a2 + x2 + b2 - 2bx + x2X c2 = -a2 - x2 + b2 - 2bx + x2
