So here is how we are going to find out what is ED. Based on the given figure, it states that, AE is 10, and EB is 4 and CE is 8. So, <span>(AE/CE)=(ED/EB) 10/8 = ED/4 <<multiply both sides by the common denominator which is 8 and the result would be: 80/8 = 8ED/4 10 = 2ED <<divide both sides by 2 and we get ED = 5. Therefore, the measurement of ED is 5. Hope this answer helps. Let me know if you need more help next time!</span>
