STEP 1: find height h
To find height h use formula:
sin(α)=ah After substituting α=60o and a=1cm we have:
sin(60o)=1h 23=1hh=23⋅1h=0.866 STEP 2: find diagonal d1
To find diagonal d1 use formula:
sin(2α)=d1h After substituting α=60o and h=0.866cm we have:
sin(260o)=d1h sin(30o)=d10.866cm 21=d10.866cm d1=210.866cm d1=1.7321cm
