Triangle ABC is inscribed in a circle such that A and B are the endpoints of a diameter. CD is the altitude drawn to AB. If AC=15 and BD=16, compute the value of (AD*BC/CD)-3

  • Math - ,

    C is the right angle => triangles ADC and CDB are similar.
    AD/AC=CD/BC =>(AD*BC/CD)=AC

  • Math - ,

    if I follow your work then

    AC is 15 -3

    Final answer 12
