Given: AACD is isosceles with angle D as the vertex angle. B is the midpoint of AC. AB= x + 5, BC= 2x - 3, and CD = 2x + 6. Find
Marina86 [1]

Answer:

  • 70 units

Step-by-step explanation:

<u>Given triangle ACD</u>

  • AB = BC
  • CD = 2x + 6
  • AB = x + 5
  • BC = 2x - 3
  • P = ?

<u>Perimeter is sum of the side lengths:</u>

  • P = AD + CD + AC

AD = CD because D is vertex and the triangle is isosceles

AC = AB + BC because B is midpoint of AC

<u>Then P is:</u>

  • P = 2(2x + 6) + (x + 5) + (2x -3) = 4x + 12 + x + 5 + 2x - 3 = 7x + 14

<u>Find the value of x from the AB = BC:</u>

  • x + 5 = 2x - 3
  • 2x - x = 5 + 3
  • x = 8

<u>Then find the value of P:</u>

  • P = 7*8 + 14 = 56 + 14 = 70 units
