In right triangle ABC, we are given that ∠ABC=90∘ and AC=34. D is a point on line segment BC such that BD=12,DC=18. What is the length of AD?

  • Math (Geometry) -

    from the information,
    BC = 30
    so AB^2 + 30^2 = 34^2
    AB = 16

    Then in triangle ABC
    AD^2 = 16^2 + 12^2 = 400
    AD = √400 = 20

    math sucks
