Question

Can anyone please help me find the length of X?
​

Answer 1

Note that:

• 2(Perimeter of smaller triangle) = Perimeter of larger triangle

Using the perimeter of the smaller triangle, solve for x.

• 2(Perimeter of smaller triangle) = Perimeter of larger triangle
• => 2(3.5 + x + h) = 7 + 4 + 2h
• => 7 + 2x + 2h = 7 + 4 + 2h
• => 2x = 4
• => x = 2

The length of x is 2 units.
