panjang tangga miring = [tex]\sqrt{}[/tex]tinggi tangga^2 + jarak tangga^2
jarak tangga = 1.5m
panjang tangga = 2.25m
2.25 = [tex]\sqrt{}[/tex]tinggi tangga^2 + 1.5^2
5.0625 = tinggi tangga^2 + 2.25
tinggi tangga^2 = 5.0625 - 2.25
= 2.8125
= [tex]\sqrt{}[/tex]2.8125
= 1.677 cm
tinggi tangga dri tanah = 1.677 cm
