Ex 6.2, 1 In figure(i) ,DE || BC. Find EC in (i) It is given that DE II BC Hence , / = / Putting the values 1.5/3 = 1/ 1.5 EC = 1 3 EC = (1 3)/1.5 EC = 2 cm Ex 6.2, 1 In figure (ii), DE || BC. Find AD. It is given that DE II BC Hence , π΄π·/π·π΅ = π΄πΈ/πΈπΆ Putting the values π΄π·/7.2 = 1.8/5.4 AD Γ 5.4 = 1.8 Γ7.2 AD = (1.8 Γ 7.2)/5.4 AD = (18 Γ 72 Γ 10)/(54 Γ 100) AD = 72/30 AD = 2.4 cm
