Explanation: This question can be solved using two methods: Method #1: From the image, we can note that D is the midpoint of EB, therefore, ED = DB This means that: EB = 2*10 = 20 units
Method #2: From the image, we know that ED = DB We are given that ED = 10 units Therefore: DB = 3x - 8 = 10 3x = 18 x = 6 DB = 3(6) - 8 = 18 - 8 = 10 units EB = EB + DB = 10 + 10 = 20 units
