Answer:

x = 4

Step-by-step explanation:

Perimeter of triangle = sum of all sides

Side 1: 14 - 2x

Side 2: 3x - 1

Side 3: 2x + 1

Perimeter= side 1 + side 2 + side 3

26 = 14 - 2x + 3x - 1 + 2x + 1

26 = 14 - 1 + 1 - 2x + 3x + 2x

26 = 14 + 3x

3x = 12

x = 12/3

x = 4

Multiply 2 and 3 also multiply 4 and 5 and then divide the products together like so 2x3 divided by 4x5 so 6 divided by 20

Answer:

The height of the triangle h is 5 cm.
