Question

In figure AB EF and CD are Parallel Lines given that AB = 15 EG = 5 cm GC = 10 cm and DC = 18 cm calculate EF and AC​

Answer 1

Answer:

9cm

Step-by-step explanation:

In Δ GEF and Δ GCD, we have

∠EFG = ∠GCD (Alternative angle)

∠EFG = ∠CGD(Vertically opposite angles)

Δ GEF ~ Δ GCD

Thus,

GE/CG = EF/CD

or, 5/10 = EF/18

or, EF = 9 cm.
