Given \small \Delta ABC\sim\Delta DEC, could you use the proportion \small \frac{9}{10}=\frac{8.75}{EC} to determine the measure of EC? If yes, type yes and solve for EC. (Must type yes and give value of EC) If no, type no and rewrite the proportion and then solve for EC. (Must type no, give the correct proportion, and the value of EC)
