  • How about a right triangle when the height length is not known base is 5cm and the other segment is 13cm but the height segment is unknown. im losing my mind

  • thanks again I totally forgot all that

  • This video did not mention the units of measurement, but the units will always be squared (or have an exponent of 2) when area is calculated. units of height x units of base = units squared

  • 35=.5×10×height

    35/.5 = 70

    70/10 = height

    height = 7
