Question

Find the missing length.

Answer 1

The missing length is 45

Explanation:

CD || AB

`\mathrm{\cfrac{EC}{AC} =\cfrac{ED}{BD} }`

`\mathrm{\cfrac{20}{8} =\cfrac{?}{18} }`

`\mathrm{\cfrac{?}{18}=\cfrac{20}{8}}`

Cancel the common factor, which is 4:-

`\mathrm{\cfrac{?}{18}=\cfrac{5}{2}}`

Multiply both sides by 18:-

`\mathrm{?=45^o}`

Therefore, the missing length is 45.
