Triangle ABC is a right triangle such that m angle B= 90 degrees. If AC= 12 and BC=9, what is the perimeter of triangle ABC ? round to the nearest tenth.

  • geometry -

    Use the Pythagorean theorem.

    (AB)^2 + (BC)^2 = (AC)^2

    Insert the values in the equation above and solve for AB, then add the values for each side to get the perimeter.
