Answer:

[tex]\large \tt { 16 \: \: \:feet }[/tex]

Step-by-step explanation:

Setting up the equation, establish the best proportion.

  • [tex]\large \tt \dfrac{x}{40}[/tex] = [tex]\large \tt \dfrac{20}{50}[/tex]

[tex]\: [/tex]

Solving the equation, setting up the ratios and then cross multiply.

  • [tex]\large \tt \dfrac{x}{40}[/tex] = [tex]\large \tt \dfrac{20}{50}[/tex]

  • [tex]\large \tt {(x)(50 \: ) = }[/tex] [tex]\large \tt {(20)(40)}[/tex]

  • [tex]\large \tt {50x \: = }[/tex] [tex]\large \tt {800}[/tex]

  • [tex]\large \tt \dfrac{50x}{50}[/tex] = [tex]\large \tt \dfrac{800}{50}[/tex]

  • [tex]\large \tt \purple {x \: = \: 16 }[/tex]

[tex]\:[/tex]

∵ Therefore, the short ladder reach the wall up to 16 feet.
