According to the Pythagoras theory, 10:6=L:H1 and 10:√(102-42)=L:H2. Then, H1=6L/10 and H2=√84L/10. Hence, H1:H2=6L/10: √84L/10=6: √84
=6:2√21=3:√21. The correct answer is A.

Hi MathRevolution,

I really appreciate the question but would it be possible for you to provide which segment has what measurement along with the nomenclature ?
Currently, its a little difficult to identify.

Thanks in advance ! :)
