Step-by-step explanation:

ΔABE and ΔACD are similar hence the ratios of corresponding sides are equal, that is

$\frac{AB}{AC}$ = $\frac{AE}{ED}$ = $\frac{BE}{CD}$

Using the first pair of ratios then

$\frac{20}{5}$ = 4 = $\frac{26}{ED}$ , hence

4ED = 26 ( divide both sides by 4 )

ED = 6.5 cm

(b)

Similarly

$\frac{BE}{18}$ = 4, hence

BE = 4 × 18 = 72 cm
