  • 1.4²+b²=3.1²
    1.96+b²=9.61
    b²=7.65
    b=√7.65
    b=2.8(rounded to the nearest tenth)

    5²+12²=C²
    25+144=c²
    169=c²
    c=√169
    c=13cm

    6²+3²=c²
    36+9=c²
    c²=45
    c=√45
    c=6.7ft ( rounded to the nearest tenth)
  • a² + b² = c²
    1.4² + b² = 3.1²
    1.96 + b² = 9.67
    -1.96         -1.96
               b² = 7.71
                b ≈ 2.78
    -----------------------------------------------------------------------------------------------
    a² + b² = c²
    5² + 12² = c²
    25 + 144 = c²
    169 = c²
    13 = c
    -----------------------------------------------------------------------------------------------
    a² + b² = c²
    6² + 3² = c²
    36 + 9 = c²
    45 = c²
    6.71 ≈ c
