Isosceles 67744

Two isosceles triangles have the same angle at the vertex opposite the base. The first one has a base of 12 cm and a leg of 9 cm. The other has a 16 cm long base. Calculate the perimeter of the second triangle.

Correct answer:

o2 =  40 cm

Step-by-step explanation:

a=12 cm r=9 cm  b=16 cm  Δ1   Δ2  k=b/a=16/12=341.3333  r2=r k=9 1.3333=12  o2=b+r2+r2=16+12+12=40=40 cm   Verifying Solution:   o1=a+r+r=12+9+9=30 cm  o3=o1 k=30 1.3333=40 cm o3=o2
