Question

two equel sides of an isoceles triangle are each 2cm more than trice the third side. if perimeter of triangle is 67 . find length of its side​

Answer 1

Answer:

Step-by-step explanation:

Let the third side be x

The other two sides will be 3x+2 each

Perimeter=67

x+(3x+2)+(3x+2)=67

7x+4=67

7x=63

x=63/7

x=9

The third side is 9cm

Answer 2

Answer:

Third side of triangle = 9 cm and other two sides are 29 cm

Step-by-step explanation:

let the third side be x

other two sides will be 3x+2

perimeter of triangle =67

x + 2× ( 3x + 2 ) = 67

x + 6x + 4 = 67

7x = 63

x = 9 cm

and 3x+2 = 29 cm

so the 3 sides of triangle are 9cm , 29cm and 29 cm .
