Question

plz guy help me ok ​

Answer 1

(i) here, DE ll BC (given)

so, AD/ DB = AE/ EC. ( by Thals theorems )

= 1.5 / 3 = 1/ EC

= 1.5 * EC = 3*1

= EC = 3/ 1.5

= EC = 2

(II) here, DE ll BC (given)

so, AD/ DB = AE/ EC

= AD / 7.2= 1.8/ 5.4

= AD* 5.4 = 1.8*7.2

= AD = 1.8*7.2/5.4

= AD = 2.4
