Question

LH=45 and KH=30, find HI.

Answer 1

`HI=20`

Explanation:

`\widehat{HKL}+\widehat{HKI}=90°, \widehat{HIK}+\widehat{HKI}=90° \\\Rightarrow  \bigtriangleup HIK\cong\bigtriangleup HKL\Rightarrow (HI)/(HK)=(HK)/(HL)\Leftrightarrow HI=\frac{{HK}^(2)}{HL}=(30^(2) )/(45)  =(900)/(45) =20`

Answer 2
