Question

Find X on the figure shown

Answer 1

`x=30\:cm`

Explanation:

`(x)/(45)=(18)/(27)`

`x=(18*45)/(27)`

`x=(810)/(27)`

`x=30`
`cm`

-{ModPatrol}

Answer 2

x = 30 cm

solve proportionality:

`\sf (larger \ side)/(larger \ base) = (shorter \ side)/(shorter \ base)`

solve:

`\hookrightarrow \sf (x)/(45) = (18)/(27)`

`\hookrightarrow \sf {x}{} = (18*45)/(27)`

`\hookrightarrow \sf {x}{} = 30`
