Given:

  • Angle ACB = 90 degrees

  • CD is perpendicular to AB

  • AD = 4cm and BD = 9cm



To find:
Ratio BC:AC

Solution:

  • Step 1: Draw the figure

  • Step 2: Label the figure with the given measures

  • Step 3: Use Pythagoras theorem to find the value of CD.
    CD^2 = AD^2 + BD^2
    CD^2 = 4^2 + 9^2
    CD^2 = 97
    CD = sqrt(97) cm

  • Step 4: Using trigonometric ratios, we can find the value of BC and AC.
    tan(ACB) = BC/AD
    tan(90) = BC/4
    BC = 4 x tan(90)
    BC = infinity

    cos(ACB) = AC/AD
    cos(90) = AC/4
    AC = 0

    Therefore, the ratio BC:AC is infinity:0 or undefined.



Answer: The ratio BC:AC is undefined.
