Annette [7]

Answer:

Perimeter = 78.7 inches

Step-by-step explanation:

From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;

/hyp/^{2} = /adj 1/^{2} + /adj 2/^{2}

          = (29)^{2} + (9)^{2}

          =841 + 81

/hyp/^{2} = 922

hyp = \sqrt{922}

      = 30.3645

The perimeter of the triangle can be determined as;

perimeter = l_{1} + l_{2} + l_{3}

                 = 30.3645 + 18 + 30.3645

                 = 78.729

The perimeter of the triangle = 78.7 inches
