An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 9 inches, and the length of the base is 7 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

Answer:

P = 26.4 inches

Step-by-step explanation:

3.5² + 9² = c²

12.25 + 81 = c²

c² = 93.25

c = √93.25 ≈ 9.7

so 9.7 are the lengths of the sides opposite the congruent angles

P = 9.7(2) + 7

P =  19.4 + 7

P = 26.4 inches
