Answer:

answer is 20

we know that,

perimeter of a triangle =all sides of triangle.(ie.A+B+C)

LIKEWISE..

perimeter of 1st triangle

=5+x-5+x-4

=2x-4

again,

perimeter of 2nd triangle

=16+10+x-10

=16+x

now according to question

perimeter of 1st triangle =perimeter of 2nd triangle

2x-4=16+x

2x-x=16+4

therefore ...x=20

goblinko [34]

Answer:
